Yeah, I personally really love the graphs that I don't have to manually enter data for, like my weight (withings scale) or any time-based goal [http://tagti.me] or pushups (sort of, thanks to an Android app that Bethany Soule wrote [1]).

Thanks for the kind words, and be sure to upvote the API suggestion here: http://beeminder.uservoice.com/forums/3011-general/suggestions/2281597-publish-the-beeminder-api-

Oh, and note we have an SMS interface: http://blog.beeminder.com/textbot (US only, unfortunately; via Twilio)

[1] It counts pushups by touching your nose to your phone. You still have to enter on Beeminder but it's an odometer-style goal so no need to enter every day. It would actually be pretty easy to connect it to Beeminder so no data entry is needed at all, if there's demand for that...
