I'm surprised posts aren't restricted a bit more. Maybe that's just my old school "lurk moar" mentality, but I feel like I really need to understand the vibes of a community before I start to contribute posts to it.
Yeah, exactly. Thirteen years ago, I was a lurker. No account, because why would I make an account just to read? But when I wanted to say something badly enough, I made an account. (I think the first thing I did is post an Ask HN about functional programming, so "no posting for X time" might have turned me away.)
