This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
I'm not sure what multiplying the number of posts with the number of users accomplishes (maybe that was just a figure of speech?), but by now we have something like 370.000 discussion threads (and thus a multiple of that in individual posts).
The raw number of posts is not really a problem, as most of them are old and inactive. On any given day there are usually no more than around 400 active topics. Over time, the posts do take up more storage, but with storage costs being what they are these days, that's not something to worry about. What will degrade over time is searching through the archive of posts. Let's hope that the algorithms used by Lucene get better faster than the search is getting slower through an increasing number of posts...
