I found a very helpful article on One Cool Site today and (after asking permission of the host) attempted on two different occasions to reblog the post from my WordPress Reader. Both times, the reblog wording at the bottom left initially changed to say "Reblogged" and showed the reblogged icon, but when I later went back to check on it, this was reset (as if it hadn't been reblogged). When I checked both sites (i.e. mine and the original), I saw no evidence of the reblog there either. The One Cool Site host suggested that I report this to the support forums.
The blog I need help with is chrismcmullen.wordpress.com.
