Only looking for a change - which means somebody may have replied, and I'll want to be polite and check that out. I don't remember anything but the last 2 digits short-term.
Pretty much this, I find some of the best internet conversations can be had on this website and there are very intelligent people here so I check a few times to see if someone responded more than for karma. I don't think my ideas fit into the mainstream too often so the karma doesn't do much for me lol I also drop accounts and start new ones.
