I had this browser(Flock) from the day it was first released and had no major problems.
Go ahead and get it..its cool and the reason is you get to do cool things with it. I am not going to repeat all those here except for this one- Blogging directly from the flock browser. If you see something interesting while your browsing you can just copy a quote or link, hit the feather button on the browser which opens a new window then point to your blog and paste you content or add new content and publish.
Yes this blog was done that way- from FLOCK browser.
