There’s been a lot of talk about a service called OnlyWire that allows you to schedule and share posts on dozens of social networks at the same time. Does anyone have any direct experience with this? How can you share a post to a social network you don’t belong to? 

@andrea-vahl Thanks, Andrea. The site makes it sound like it’s just the push of a button and you can multiply your posts to all these other networks. It does not mention that you actually have to belong to these other networks. 
My goal was to look into providing a viable service to clients by being able to multi-post to increase their exposure. Do you know of any way this is possible? Or are all these services just smoke and mirrors?
