Seems like I have made a comment in Blogs and it's not showing up on activity wall? I also somehow managed to add Comment to activity wall and that has disappeared also? Am I missing something?

Are Blog comments shown in Activity Feed? Also yesterday I somehow got permission to directly edit Comment on dnnsoftware.com home page Community Live Feature? Is this even possible? I think it was after an upgrade or something, but shouldn't this activity show up on the Activity Feed?

Any help or guidance understanding would be appreciated, thanks.
