Here was an interesting little experiment:
Is there a Word Lens alternative/port for Android?
I knew that "Word Lens" was a hot topic yesterday, and that question it turned out to be the most viewed post yesterday. In fact it's gotten 219 views in the last 20 hrs where as the next most recent post to get 200 views was asked on the 8th, taking a week and a half to get to 282 views. Of the most popular search terms that brought people here over the last day "word lens android" got 90 and the next most popular was Samsung i5500 2.2 with 6 visits.
Now as far as questions, this wasn't the best one on the site, and it probably wasn't very useful to building membership because people probably came here found that there is no such app and left.
The value of the experiment is that it goes to show how being mindful of whats trending and making good titles with good keywords is helpful in getting people here. Now ideally if we are to seed questions based on hot topics they'd actually be useful (Like Al's "When will my phone get Android 2.x?" questions) so when they get here they find some value and stay.
