This looks like a solid plain text, own your own data, replacement for a service like iDoneThis. I should try and get my iDoneThis for Alfred plugin to post updates via doing and iDoneThis so I can keep a personal archived record of "dones" as well as share with my team via iDoneThis.
After I publish the next release (which includes flagging and archive by tag), my next thought is to give it nicely-styled html output as an option. It can currently do CSV, but a ready to go page that could be sent to Dropbox and update a web page would be handy for some. Or even for GeekTool users…
