&gt; The major downside, as I see it, is that it&#x27;s just not as popular.<p>Has anyone really thought of this?  Do people just happen on to a github project because &quot;it is on github&quot; or because someone linked their work and people liked it and wanted to contribute?<p>Would React, D3, Rails, Bootstrap etc not get what they do now simply because &quot;oh I don&#x27;t have a bitbucket account, I&#x27;m not going to bother&quot;<p>To me at least this kind of argument (I hear a lot of, nothing personal davesque!) is along the lines of &quot;everybody is on MySpace&quot;
