Zillow.com reports that Realtor Marney Kirk is ahead in the battle for the "best real estate blog in Baltimore" title by one vote, last they counted. The Real Estate Wonk blog is No. 2.

"The rest of the gang is within a dozen votes, so it’s a close battle," says Zillow's Matt Bowers.

Baltimore is one of 10 cities with best-blog contests. Others include Philadelphia, Chicago and San Diego.

It's interesting to watch the role of social media here. Bowers says blogging about the contest is helping contenders -- of course -- but tweeting and Facebook updates are making a difference, too.

So on that note: Vote! This is one-vote-per-day contest, which means you can register your opinion frequently between now and Aug. 11, when it's all over.
