Inbox by Gmail

This is a lot like what @paulg was talking about on his &quot;Frighteningly Ambitious Startup Ideas&quot; essay when he talks about replacing email: <a href="http://www.paulgraham.com/ambitious.html" rel="nofollow">http:&#x2F;&#x2F;www.paulgraham.com&#x2F;ambitious.html</a>

And this is....what, exactly? My Gmail account already has an inbox.

Never understood this obsession with &quot;reinventing email&quot;. Email works fine. Use filters, folders, tags and full-text search.
