I would imagine there are a host of reasons:
1) if you say you are just lurking lately, I bet there are alot of others doing the same
2) I don't have to mention the economy SUCKS! Less lesiure time, less money/time for internet, people losing their jobs or working two to make ends meet, people losing homes much less internet access.
3) "Life is what happens when you are busy making other plans" J. Lennon

This pesky "responsible adult" stuff is a pain! LOL!
