Ya know, I’m starting to be surprised this hasn’t been done yet (maybe it’s hard), but what we really need is an app (or web app) that acts as a front end for composing POSSE posts, and:

• Gives you various indicators/metrics as you type of the character limits of each of SEVERAL social media apps to which you wish to crosspost;
• The ability to include multiple links and indicate which one is the most important for those stupid sites that only embed one;
• Ditto images;
• Maybe makes it REAL EASY to provide summary slugs w/in character limits for various social media sites;
• Tagging in a way that meshes with each of several different social media apps….

And probably a bunch of other stuff I can’t think of off the top of my head.
