Ever heard of beantowbanter.com?

It's a Boston sports blog, take a look.  The other day I tweeted my Tommy John surgery link at them, and they started following me.  So then I sent them some more stuff, and now they've asked me to be a contributing writer.  The site has 7,430 twitter followers and 2,713 facebook "likes," so there are clearly a lot of people that read it.  It's definitely more serious and less sarcastic than Cosby Sweaters, but it's also local and specifically about the teams I care about.  Obviously I want to write for both sites, but it's probably not cool to post the same things on each.  I'm not sure what the protocol is for blogging though.  Are there any rules/journalistic integrity?  I get the feeling it's kind of like the Wild West out there in the internet universe.  I've definitely found my blog in other places where people just stole it and reposted it somewhere else.  Regardless, this is becoming a lot of work for a hobby.  I think I may need to cut back the hours at my actual job.
