I’ve added the wordpress.com feed for all posts tagged as interactive fiction, no matter what blog they’re from. I don’t know if this is a good idea. If you think it brings it too much non-IF stuff let me know and I’ll remove it.
I don’t know exactly what’s doing it, but you’re getting some alladdictinggames links that you don’t want. (For my $0.02, though, I’d rather have them if that’s the price of keeping the “interactive fiction” tag.)
