Ah, are you talking about constantly checking your computer for new messages, refreshing it every half hour, even though you know there probably won't be any, just to put off doing something more important?
I've been there. However, for me, there was a certain meaning to it. The meaning was that 1) I wanted to see the reaction to my messages IMMEDIATELY, and 2) I wanted to know what others were up to in general (in particular, what my virtual acquaintances and real friends, who hang out in the same online community, are doing – what's happening in my country and in the world in general).
I don't really do that anymore. Maybe because my main interests have moved to the real world. And pointless activities have moved there too – like going to a store even though I don't need to buy anything.

Oh, and I'll finally answer the question – yes, I still do that. Considering that I'm a WORKING person who also needs to spend time on eating and sleeping, I get incredibly frustrated when I realize that I spent a whole hour doing absolutely nothing.
Where do we end up when we save the world?
