I totally understand that. I keep in touch with a couple of folks that are in the same boat, and I am too. Having an extremely intelligent and active two-year-old and 15 weeks from a newborn baby boy has me totally balls to the wall - and that doesn't include the 5-hour work week.
I was just sitting here reminiscing last night about the people who, after I signed up, really had a huge impact and have been visibly missed. I know some folks (Cathy, for example) post once every 6-8 weeks, so they're still around, but I still think about those folks from time to time as well.
Certain people here have made an impact on my life, internet or not. I didn't list everyone, I just pegged off the people I rarely see post these days or people I don't email with, text or call regularly.
