It could trigger flaming I think.
Hey, this minute (yes, sometimes I hit the update button a lot) my score dropped drastically. Which *holes are voting me down, lets see.......
Ben's idea might be a little too much but..... it would be nice to be able to let someone know you would like to send them a meaasage, ask a question, or the like. It would be a kind of instant gratification sort of thing. Maybe some sort of little message jumps up on the page they are on that says :Hey XXXXX, So ans So wants PM you, then they could check and you all could take care of business.
If this is a dumb idea say so.

I like your idea Konador, this could be fun... and make this domain more alive ... but I think it could be hard for the web-dudes to tell exactly what people are doing and for how long they'we been up to it...
