Does anyone have advice on whether I should start a new group on Yahoo! or Big Tent?

I belong to groups on both yahoo.com and bigtent.com. Now I want to start my own group - does anyone have any advice? What are the advantages or Yahoo! Groups vs. the advantages of Big Tent groups?





Any advice would be super helpful.
