Khürt, I can feel your pain. I know that SNAP just made a recent major release that changed a lot of it's code base, so I've been half purposely waiting to update while they work out some of the kinks. I'm just about to download the most recent and test it out on a server before I upgrade to the latest version on my production site, since the old version is still doing a relatively good job and it's a lot of overhead to update/upgrade going into the holidays.
There's a frequent phrase that many in the chat will use: #ManualUntilItHurts by which they mean try doing everything manually to work on getting the output and workflow to work the way you want it to and only then try automating things based on your manual experience.
There are many ways of doing syndication, so before settling on one, try doing things by hand for a bit while you're testing out other potential options. I often find that even though I've got automated means of doing things very quickly, I actually often prefer the manual methods sometimes, particularly when it means I know exactly what the output will be. With POSSE you'll find that with some of the automated means, the easier it is to set up, the less options you'll have for control, while the more control you get means a much more difficult set up.
Try a few options and then go with what works for your needs until it drives you so crazy you have to change it. In the meanwhile, documenting the issues and problems either on your site or in issue queues will slowly help things get better.
In the end it can't be much worse than people who are syndicating their Facebook content to Twitter that simply shows up as just the raw https://fb.me/123456789 URLs and nothing else. 😉
