Online dating site Chemistry.com continues to embrace the gays.

Brandweek provides some more details:

So what impact did Chemistry.com’s attack ads have on eHarmony? Apparently, a positive one. eHarmony saw its February unique visitor total rise to 2.8 million from 1.8 million the year prior.

On a related note, Diller last week won a court case allowing him to split his company, IAC/InteractiveCorp - which owns Match.com - into five parts. Stocks rose 3.2% this morning. We’re going to start looking for someone with IAC stock.
