blog frog? what is it?

ok, i just joined blog frog as part of the spring fling going on and i don't really know what it is, i mean i already have new followers (awesome and thanks)  but can someone tell me what i'm supposed to do and what the point is?
oh and i updated lacycakes with more new projects. check sidebar for link.

now for important stuff. colter is getting a tooth! he is also starting to lose some of the chubkins-ness. NO! I want him to be my fat baby forever. he just wants to be one of the big kids though.  and the big kids are busy, easter was fun! the bunny hopped through our very own back yard for the first time, and what a beautiful spring filled backyard we have. It's fun!
