Twitter may not be good for much beyond wasting time, but every now and then there's something that pops up that is worth knowing.
Literary agents who are active on Twitter often send out a tweet announcing that they are open (or closed) to queries. Getting yours under an interested nose at just the right time, when interest is high, can be enough to get a request for the manuscript.
It's all about timing, after all.
The same can be said of publishers. There are plenty of them out there, both small and large, and many of them maintain a twitter feed.
By and large, they use the Twitterverse to broadcast new releases or display little pieces of good reviews. It's all about sales. Twitter is just another marketing venue.
But at the same time, an editor might use those precious few characters to mention a shortage of some particular type of manuscript, or a certain genre that would be hot if they could find the right story right now.
Thanks to Publishers Weekly, you can browse a list of publishers on Twitter and find those that might be of some use to you.
You never know what someone might tweet, unless you follow.
As for all that Pinterest blather, there's got to be a limit to how much time you waste online.
You're supposed to be writing, don't forget.
