Over the past weekend I purchased the domain building-cincinnati.com.
While this is not ideal (having to mention the "dash"), it was the best I could do to still get a ".com" address.
About a month ago somebody purchased buildingcincinnati.com. I haven't found out who bought it (although I have a couple of guesses), but they have basically thrown away about $30. Great business move.
Look for this blog to eventually migrate to the new address. I'll be sure to let you know before that happens.
