I started with a blog/photo blog of sorts, then a little while ago decided to sign up with Smugmug (was debating between Smugmug and Winkletdesigns and doing it myself using say Gallery 2.0, but I like features offered by Smugmug - right click protect, no print option, etc)
My experience has been that a good blog actually does work to generate interests and referral traffic, as long you keep it interesting and fresh
