Right clique

Before I start, I just want to point out I do see the irony of referring to geeks on the internet within a blog post, so please don't feel the need to point that out.  I already know.

So anyway, 4chan.  Some of you may already be aware of the existence of this site, it's been around for years and certainly has a cult following, especially the /b/ board.  The /b/ board on 4chan is the random topic board, where users post about anything they feel like.  Usually it's pictures of girls, often baring their breasts.  Which isn't necessarily a bad thing.  Actually, thinking about it, more often it's porn, but what the hey?

These types of board have a dedicated group of users (I'm not picking on /b/ here, simply using it as an example), all of whom have their own rules, conventions and language.  You'll often see posts saying "Tit's or GTFO", or "MOAR!" in reply to posts containing pictures of young ladies, or phrases such as "Obvious troll is obvious".

This is all well and good, to a point.  There's nothing wrong with a group of people who speak to each other in a way nobody else understands.  Look at the Welsh.  However, the users of these boards to seem to be very cliquey and are extremely quick to jump all over someone who's not 100% down with the conventions of the board.  Feel sorry for the poor n00b who posts something without first understanding how the board works.  

Is this strictly necessary?  After all, these boards surely only thrive because new users come along to replace those who have moved on because they've grown bored / been banned / ended up in jail?  Shouldn't new users be encouraged to join discussions, and be able to rely on a little guidance from more experienced users?

No?  I'll shut up then and get back to attacking newfags on /b/...
