Because unless you're Tim Duncan there's a fine line between posting and spamming, check out Queued.at: built out in Big D over the course of a 54hr startup competition, this downloadable program analyzes an enormous amount of data -- including your own -- to determine what, when, and where both businesses and casual users should post on the Internet. What the service entails:
Network Suggestion: Upload whatever content you're looking to disseminate, and through keyword analysis of both general trends and your unique posting history, Q/A will determine its optimal outlet (Facebook, LinkedIn, Twitter, etc), giving you the most bang for your buck, though technically last time the Bucks had bang, a certain 7'2" Muslim was still a Lew.
Efficient Scheduling: The program will also recommend optimal times to send out various types of content depending on which network you're using -- though if you're using The Social Network, you'll always want to send things out late at night, when the rich kids are having cocaine-fueled orgies with girls they've bussed in from schools that aren't Harvard.
Post Throttling: Saving you time and your contacts aggravation, this function lets chronic posters load up all their day's send-outs at once, after which the program will space them out for you, with the intervals becoming more optimized as it learns more about just much time must elapse before you're forgiven for exposing people to a turtle humping a shoe.
It'll also track and consolidate clicks, comments, and re-tweets across all networks and accounts, and they're working on a content-suggestion feature that'll actually tell you what kind of info you should be posting based on what your recipients seem to be responding to -- just remember, the line between Reuters stories and p*rn is actually pretty thick.
