I stumbled across your blog and have really enjoyed reading all your posts. That said, I have been thinking about your letter and "could have gone better" post off and on since I read them.
Specifically, I wonder if I were in Donna's shoes, what would my reaction be? I think it would be really hard to jump in and "have a voice" on a site that has painted perhaps a somewhat one-sided view - a cariacature (sp?) that includes frigidness, inflexibility, laughable beliefs (the way that hers are presented here) and waaaaay more information about her underwear habits than she might tell a load of interent strangers.
I do hope for the best for you and that this works out, but at the same time I guess I have taken the lesson that I A) will be more careful about how I talk about people in my own blog and B) always ask my SO if they have a blog and can I see it, so something like this doesn't bite me in the butt.
good luck!
