please excuse me since I'm at work and haven't read all your comments yet but I get what you're saying and I'm not disagreeing with it.
I have received all my comments from the tagged results from WP pages. To answer one question. Only one comments from another blog outfit. Tumblr. Only one does.
I have an issue of "liking" things I really don't just to draw likes to me. I'm sure that's not what you're suggesting in total bird but I'm just saying. I do respond to all comments.
My main point is not if Tags are the most affective at anything. It's the obvious disregard from "support" when the issue is obvious. I don't know how much more a thing can be proven than it was. I still don't have any posts from that blog showing up. yet since correcting the "poem" to "poems" on the other blogs, each and every post shows up all the time ever time. Regardless of the 31 mill blogs.
