I was probably one of the first to use the blog tool as a means of publishing TG erotica.
This year there has appeared several new blogs presenting transgender caps, and some of them publish new caps and stories on a regular basis.
You could say the blog has become an alternative to the always popular Yahoo! groups for publishing such content. This is partly caused by the fact that Google's blogger accepts adult material.
I have put up a list of some of the new blogs over at TFCC.
And please tell me if you know about others!
