Oki, this is a little off topic, but it was talked about here so I'll add it here.
I maybe found a pattern in the featured user thing, at least by me it shows the last one I've searched, not the last I was with, but the one I've typed in the search engine … thing. Still there's the thing with sometimes showing myself, 'cause I don't search for myxself of course, but well, beside this, it always shows the last user, that I was actively looking for. In my case it's one of my friends, that I look after pretty frequently. Once it was a user I just typed his name in and then logged out. I may be wrong and it could be random (what do I know about how it works, but for random, there's too much of that one particular friend of mine in there), or another pattern in it, but it looks that way for me.
Sorry for being off topic, but the main thing was fixed and I didn't want to start a whole new topic just about the featured user thing.
