I suppose that is true. What I'm looking for, however, is some way to chat with others about questions like:
"Out of all the blogs that cover research in Chicago, which one do you feel is the most helpful?"
While there is a search engine to find blogs, there are so many out there that finding and evaluating what's best can be a challenge. They do, however, have some neat material. I'm always wanting to find more places like that. And, from time to time, I've been in situations where someone I'm talking to turns out to benefit from suggestions I've made, too.
It's just another avenue to pass along suggestions concerning genealogy research.
