The tools use our own technologies (talk about dog food) so they work, look, and integrate beautifully. Best part, if someone doesn’t like something, well, they can just fix it. (To wit, our email and calendar software is off-the-shelf and is the most unpleasant tool to deal with. Get this – we have a few people “specialized” in sending large meeting invites out, because there are bugs that require peculiar expertise to work around. Not to mention that such invites come with “Do not accept from an iPhone lest you corrupt the invite for everyone!”)
Nice to know big tech companies can’t fix calendaring either. Also, while we’re here, I liked this comment about Facebook’s use of PHP:
Facebook’s outlook of PHP is largely passionless; yes, engineers understand it is far from perfect, and people occasionally rant or show some WTF code sample. At the same time, at Facebook we love doing cool things, and PHP is simply a means to an end. With our extensive framework and libraries, it’s also often the simplest means to an end.
