^What he said.

Except it's more "GET OUT MY BUSINESS" than laziness. I like interacting with people on this forum. But I do not like being guilted into interacting with people on this forum. If I haven't responded, I just haven't, it's not personal. And if someone DOES get after me about why haven't I responded, it will take me even longer to respond because now I'm put off.

If I'm invisible, no one asks why I viewed my profile and didn't immediately respond. So I don't get irritated and ignore people. It's best for everyone.

tl;dr: I'm a snotty bitch.
