My main complaint is that services such as yours are not extending XMPP! By god, it's begging for it! Imagine if every e-mail service was a walled garden. Differentiate on features and user experience and otherwise embrace interoperability and you'll be better than the vast majority of chat startups out there.
Acting unilaterally when your decisions affect others deserves no praise. It's the kind of egocentric dick-waving we saw in the US in the 90s (again in the 2.0 bubble), and plenty of companies crashed and burned because of it. We need fewer glorious cult-leaders in business, not more.
Your comment is spoken from a perspective that favors the investors... not the worker who is seeking better employment.
Workers should be free to seek to improve their lives without old white men making back-room deals against them. In this regard the tech industry is no more progressive than any other, and that's incredibly disappointing. We're supposed to be such an intelligent bunch.
These are extremely superficial reasons to criticize git, leading me to believe that the author knows very little about git internals. I'll take the first critique and leave the second to someone else...
You can't pull a portion of the repo because the current state of the repo is built from the tree of commit diffs... This and the fact that git itself is a hash database leads to very efficient use of space. If you want a single folder within a repo, why isn't that folder its own repo?
Between that, the passive aggressive ;-) and the unfortunate advocacy of SVN... ugh.
