If properly advertised (.tv does not help here...) it could be a hit considering the circumstances. Developing it is not really a big deal if you use freely available blogging software like wordpress. I am almost done with blogbum.com and sexafterbaby.com - once I start advertising these sites on various forums and message boards, I hope they develop themselves as members leave their comments. Not sure if this is a good way, but it does not hurt to try. Plus, I have learned how to set up and customize wordpress
good luck!
Thanks ivoy, I'm just concerned about devoting time to it. I'd really like to do a video blog because of the extension, but that makes me a little nervous hehe.
Very true - video uploads can be a pain... But, there are ways to configure most blogging software to allow integration and embedding of videos from google video, youtube and such, which is what a lot of people do nowadays. Hope this helps!
