Yes. Me too (hence the comparision with IRC/mIRC Scripts). However this kind of communication is just purely personal, I doubt anyone is interested in the fact that some friend wanted to know how full his dropbox was at some time in the day. Maybe the _result_ is interesting, but the trigger is not.

But if this works with direct messages, i'm buying it!

(edit: typos)

I have an example in another comment of how I can buy stock with it:

CTRL @robinhoodapp buy $FB USD100

And then apart from making the transaction I can start convert with my followers about this deal. What do u think of such scenario?

Sure! By all means advertise to the world that you're about to make a trade. The HFT folks will love that.

This example is cool— the trigger here is an useful information worth sharing. You need more of theses :)

Still though, surely all of this could be done over DMs?

yes but i wanted to keep the language natural. and if you naturally want to address dropbox on twitter, then you "@dropbox" them, and not "DM @ctrltwit do something with dropbox".

moreover i realized best usecases are replies to tweets (like liking an instagram photo, subscribing to a youtube channel, saving to pocket), and those wouldn't have been possible with DMs
