I have tweeted a bunch and written some, too, about Buffer, the web and mobile app that allows you to space out your social posts and reposts and have them released at specific times during the day.
Having Buffer "baked in" as a browser extension is a killer feature.
As a user, my company has gone all in for Buffer. We are a subscriber. A business can part with much more than the that the Awesome Plan costs for a year. a year is something most businesses scrape off the bottom of their boots on a slightly wet morning.
If you see a link to this post on Twitter an hour after my last Tweet, my IFTTT-Buffer timed blog RSS-to-social setup is working.
Sure it's better to script everything locally, and I bet that piping RSS to social media at regular intervals is more than scriptable, I started using Buffer a week or so ago to spread out my Twitter posts in the event that I do a bunch of them at once.
Mind you, this hasn't yet happened. But it could. And I'm testing the service for my day job.
For my personal sites, I've been using dlvr.it to automatically feed blog RSS to Twitter (and occasionally Facebook). But while dlvr.it theoretically CAN dribble out posts at timed intervals with it's new (to me) "Q" feature, use of RSS with Q requires a paid subscript to dlvr.it. Again, for the day job this is something we might consider (if anybody but me was a dlvr.it fan), but I'm not that crazy about the paid options.
