This is smart. After the contest, anytime you search for one of the terms in their dictionary on search.twitter.com, then @engineyard will show up (assuming there are a lot of entries).
All they have to do is make the dictionary include terms that potential engineyard customers might search for on Twitter.
Not exactly 'anytime' since Twitter search history doesn't go back that far. I can't find the link now, but I'm pretty sure it only searches up to about 30 days back.
