Good for them; maybe not so awesome for the rest of us.
Updated: From Sparrow’s email to users:
We will continue to make available our existing products, and we will provide support and critical updates to our users. However, as we’ll be busy with new projects at Google, we do not plan to release new features for the Sparrow apps.
It’s been an honor and a pleasure to build products for all of our wonderful users who have supported us over the years. We can’t thank you enough.
We look forward to working on some new and exciting projects at Google!
Sigh.
