At Eyeo (8 developers, no two in the same place), we use: - IRC (most of us use IRCCloud) - Discourse (a forum, I can really recommend this even if you have chat, and Discourse is particularly good) - Skype (only used for one on one meetings) - Oovoo (like Skype, but has free video conferencing, we use it for meetings with more than two people) - Rietveld (a review system, we have mandatory reviews for all changes, really really important for distributed teams IMO) - Trello (we're in the middle of migrating to a real bug tracker (Roundup, what bugs.python.org uses) though) - Google Drive (mostly as a wiki replacement)
