Flock is EOL , Rockmelt next ?

I blog about Flock 5 years ago when it launch , but today Flock announce it will discontinued as of April 26th, 2011 , They have encourage their users to migrate over to Firefox or Chrome.

Flock started with Firefox Engine and last year they release a beta which migrate over to use Chromium engine, but it seem like this doesn’t help much.

Since Flock is closing down , it remind me another social browser – Rockmelt , the browser that deeply integrated with Facebook, will it happen to have the same fate ?

I was wondering if Flock started as plugin, will it be better ?
