I lurked for about a year, not because I was that interested in Neowin (at first) but because I have a bad tendency to open a tab and leave it open for a few weeks/months before I decide I don't need it anymore. As it happened with Neowin, I found myself browsing the forums and looking at the news often enough to register. Before that it went from a few visits every couple weeks to growing into a pretty regular thing over the course of a year.
I lurked for about a year before joining and after that too, lurking . I do run through the forum topics sometimes, but mostly its the news that interests me.
Pretty sure I joined within the first month of discovering Neowin.. maybe a bit more, but probably not much. Kept ending up here everytime I looked for an answer about something computer related so I figured joining might be a good idea.
Though I feel more like a lurker than a real member, heh.
I think I lurked for a few years before I joined. I was in no rush to sign up.. I was probably thinking I'd have nothing to share. Which was completely correct when I did sign up.
