I have blogs but haven't been very active of late because of health issues. I used to run the International Carnival of Pozitivities and still manage my own blog at 2sides2ron. I will be having surgery on my right shoulder in the near future and will be even less active during the recovery period.

What difference does it make?

And your premise is flawed—what constitutes "so many" people who have "no blogs"? (You can't demonstrate a negative. I have three blogs, but you didn't know that until now.) Who gets to be the arbiter of what constitutes a "blog"? Your question is inherently judgmental.

I haven't seen any activity by the moderator of this group for years. It would be perfectly reasonable for you to start a new tribe with more specific standards for membership.

Moderating tribes can be a lot of fun and pretty inspiring. Why not go for it? Then you'd have some place that you're sure will be more satisfying.
