I've been on this site for a few days now and what I'm discovering is that this is not Twitter or Twitter-Lite or Alternative Twitter. It may look and operate a little like Twitter but there's a different ethos, character and atmosphere here and I think it will be important for people coming from Twitter to understand this. You don't go into a stranger's house and start criticising or trying to change the way they do things. You behave politely and try to fit in. I, for one, will be treading carefully until I get the hang of it.
