Are these stats still functional? It would appear there are much less hosts than a year ago, but I read that since v0.6 it doesn't automatically connect to IRC anymore or something... Perhaps this is how the stats worked, and only some people run an old version? The website doesn't seem to suggest that's how the stats work, but still I wonder if btc is loosing users (and loosing masses, or so it would appear).
Edit: Oh, read the post above me now ^^
Note, the estimates of bitcoin client are now ~worthless
