Only an evolving medium can describe an evolving entity like the English language, especially if the entity evolves as
as the English language. Today,
is four years old, and it makes the competition look incredibly slow -- slow to keep up with the language, and slow to load in my web browser.
If you were to look up the word podcast on Merriam-Webster Online, you would be greeted with the following:

As you can see, it's not in there, but I doubt that Merriam-Webster questions the legitimacy of the word: they use the word quite often. As I write this, the root word podcast appears on Merriam-Webster’s main page four times -- once as a common noun ("this free podcast delivers a daily dose of word power and fun"). Their podcast section is even listed as a free daily feature:

Isn’t it ironic? A dictionary website, whose main draw is ostensibly to find definitions of words, uses a word that’s missing from their own dictionary multiple times on the main page! A further irony is the fact that podcasts are a free service of Merriam-Webster, yet to find out what the word means, you’d be forced to search for it at another site.
While it’s possible that the word’s definition would be available from Merriam-WebsterUnabridged.com, the by-subscription site whose link is visible in the above screenshot, this gives rise to a whole new set of questions. Google has demonstrated that low-fi content (such as dictionary data) can be offered for free in a profitable business model based on targeted advertising, even when the backend is as comparatively complex as that of Google Search or Gmail. So in the case of Merriam-Webster, this seems like a no-brainer: If you really do have good dictionary content stored somewhere, make it free! While you’re at it, cut down on the bloatiness of your site.
I know that the word podcast does indeed appear in Webster’s New Millennium Dictionary of English, as can be found through a dictionary.com query, which searches through the "Preview Edition" of that text. But why doesn’t it appear on Merriam Webster’s main page? Years ago, I relied on their site for definitions. (They won me over because they had a clever little JavaScript prompt that allowed me, even back in my Internet Explorer days of 2000, to search their site for a definition without first loading the main page.*) They lost my business soon thereafter when I started to notice that even quite pedestrian words were occasionally missing from their data. I shudder at the thought of paying a subscription fee to access word definitions, so around five years ago I stopped using Merriam-Webster’s site altogether.
What’s more, I noticed that the New Millennium Dictionary, which does contain the word podcast, is missing from the list of versions that are included in the Merriam-WebsterUnabridged.com package. This suggests that Merriam-Webster is withholding content even from paying users. But it’s not just Merriam-Webster with problems…

The above screenshot is from the subscriber-view (it would appear that my university is a paying customer) of Oxford English Dictionary (OED). As you can see, the word podcast is absent from this site as well, despite the fact that the related New Oxford American Dictionary (NOAD) named podcast their word of the year for 2006. Meanwhile, on AskOxford, they proudly announce the addition of two seemingly useless words, even while "podcast":

I applaud Oxford for leveraging the publishing power of the web to update their online version of OED four times per year, which is a bit more often than a print version could feasibly be updated. But the first question I have to ask is, “why only four?” It’s not like web publishing is all that difficult — I even manage to update my silly blog more often than four times per year, and when I do, there are quite a few more words. Further, I can’t for the life of me think of a single technical, financial, or user-oriented reason that OUP stands to benefit from the practice of buffering their updates until a predetermined day each quarter.
The OED bills itself out as “The definitive record of the English language”, yet it fails to define words like podcast and laptop, each of which has over 100 million Google hits (whereas liposculpture has abount 300 thousand) and is in daily use all over the developed world. Omissions like these are rampant in MSN Encarta Dictionary, American Heritage Dictionary (which even lacks “blog” as a term), and every other print-and-web dictionary I could find. Clearly, these companies are behind the times.
Now, I’m not the kind of tech-head that demands webization or “web 2.0″-ization of all things, but nearly everyone I know already relies on the web for definitions. And right now, they are users that are up for grabs, searching for a product that doesn’t suck; a free product that won’t intentionally omit words to solicit paying subscriptions; a product that loads quickly; a product that is up-to-date.
The product they’re looking for is Wiktionary. Wiki technology is exactly what a dictionary needs. It is a platform that thrives on changes, change-averse language pundits (see my previous entry). Because language changes far faster than the publication cycle of top-down dictionaries, a by-the-users and highly iterative approach is needed. Wiktionary uses that approach. I encourage all of you to compare your current web-based dictionary of choice with Wiktionary and see how you like it. In instances where you find it failing, you can just edit the entry and justify your changes on its accompanying discussion page. I believe that the more active users a wiki has, the more accurate and useful it becomes — especially if Wikipedia is any evidence. Because a definition can be quickly added, edited, or deleted by any reader, Wiktionary has the potential to be everyone’s go-to resource for word definitions — I know it’s mine.

*Note: Nowadays, this is possible for most of the sites I use — it’s a built-in feature in Firefox to create similar shortcuts. For instance, if I type “wp ninja” in my browser’s address bar, I get Wikipedia’s search results for the query “ninja”. I have set up similar shortcuts for about 20 sites, including Facebook search, Urban Dictionary, my university’s online student directory, and a registrar WHOIS search.
