I've been using my wordpress.com account for awhile and I'm really pleased...except for the inability to track comments. Yes, I have the feed set up (at least I think I do) but I really, really want to have people be able to subscribe to the comments. I know you can do this as a plugin for wp.org, and I can host it on my website...but I had a heck of a time figuring out how to do that initially which is why I went with the .com
Other than the lack of comment tracking for commentors, I like using .com -- so I don't have to fiddle with it so much. I'll leave feedback about my desire to have this plugin available for us .com users, but...
If I wanted to switch over to wp.org and host it on my site, would I lose all my current blog entries? Would it be like opening a brand-new blog? I can probably wrestle with it or have someone help me switch, but if it means losing everything that's there now, well...I don't want to do that.
