I too am really annoyed and disappointed about the lack of Tony/Rhody fanfic/fanart/icon in the Iron Man fandom.
Yeah, I still hope that it'll catch on eventually, although it almost seems at the moment that the production of Rhodes stuff is *slowing down*. :(

I've got your comm on my watch-list for updates, and I'm planning to do a mass-crossposting of the list soon, so I'm sure you'll see me around!
