"We're excited to announce that Sparrow has been acquired by Google!"
Hmm. Not sure how I feel about this. On one hand, I'm not as paranoid as a lot of people are about Google as I still use Gmail, Reader, Analytics, and Feedburner. On the other hand, the thing that has me a little worried is the future of the development of the apps. I use the Sparrow app on both OS X and iOS — so to me this is a little concerned as Google doesn't have the best track record with devoting time to anything that isn't Google+ or Android. Hopefully Dom and the team continue to function normally.
Update: As MacStories pointed out, an email was sent out that further hints to the future of Sparrow.
"[...] as we’ll be busy with new projects at Google, we do not plan to release new features for the Sparrow apps."
Yup — there it is.
Update 2: Just got my email too.
