I hang out here a lot too but not in all the discussions. If someone participates only or mainly in stories about VC fundings and such I may never see his or her name, while I'll probably see the name of someone who participates less but does so in technical discussions more :).

I'm on the list, I'd be surprised if anyone recognised my username who didn't know me from elsewhere.

I do recognise a good chunk of the top 30 or so names though
