Thanks so much for all the love, HN! I'll do my best to address everyones' questions in one post:<p>1) Cross-platform support: ZenHub for Firefox, Safari, and mobile is <i>coming soon</i> - how soon depends on how much our current user-base wants more platform support vs big features we have spec'd out. No worries here :)<p>2) GitHub API rate limit: GitHub has worked with us to lift the API request rate limit for users that need it, we're also limiting the GitHub API calls we do have to make with caching systems and other tactics, for eg disabling polling when you're not looking at the board. TLDR: we have no worries here either.<p>3) Major GitHub UI updates: these do have the potential to break some functionality, but our major feature (the Boards) is pretty robust. Also, we're really fast and can react to GitHub's changes within minutes if not hours. We're now working with GitHub to get a heads up on changes that may affect our product, so again - no worries.<p>4) Transitioning from Huboard / other tools: should be painless: you can even use both products in parallel during the transition period and pick the one you like best (hint: it'll be ours!)<p>5) Errors with our homepage (zenhub.io): we're fixing issues as quick as they pop up, bear with us :)<p>6) Other comments or requests: please vote on feature requests by creating new Issues or +1'ing existing Issues on our public GitHub support repo: <a href="https://github.com/zenhubio/support/issues" rel="nofollow">https://github.com/zenhubio/support/issues</a>
