Gawker Media is ditching three of its properties in an effort to focus on their core titles. The left-out trio are Wonkette, Idolator, and Gridskipper. This development leaves Gawker top honcho Nick Denton with a dozen sites.

Silicon Alley Insider has listed the new owners of the said sites:

• Wonkette: Current editor Ken Layne will take over the political site, in conjunction with ad network Blogads.

• Gridskipper: Former Gawker manager Lockhart Steele will absorb the travel site into his Curbed network; Denton is one of Steele’s investors.

• Idolator: The music site is going to Buzznet, the music site which says it doesn’t want to roll up other music blogs, but seems to do so, anyway. This was the last of the three deals to be finalized, which apparently happened over the weekend.
