I use Pocket and I like it. I don't consider it a blunder, because it addresses a problem I have and because Pocket is now owned by Mozilla, an organization that I trust. The Pocket mobile apps are also really good and polished.

I'm actually a paid customer of Pocket Premium ever since it got acquired by Mozilla.

I hope they'll open source the implementation and fix their interface — I don't like that their search doesn't have an URL that I can use as a search provider.

Also Pocket's Firefox integration is actually less invasive than Chrome's extension, which I don't appreciate. I like for example having an "add to Pocket" link on HN items or in Twitter. And the Chrome extension also gives you a homepage with trending articles on Pocket. So I don't like Pocket's Firefox integration, but not for the same reason. I don't like it because it is less capable than Chrome's.

I also have Chrome installed and try it out from time to time. But Firefox's UI is much better and I haven't had any performance issues with it, quite the contrary, for my usage patterns Firefox feels better.
