I like that we can schedule events online, which saves us time when it comes booking flights or hotels in advance of an upcoming workshop/event date! That said - if you're new at this whole social media thing then don't expect much from your first few weeks using these services as there's lots for users who've been around longer than myself to discover without having spent months learning how they work before hand (like me).
But once things start clicking into place everything works well enough so long term use makes sense given its cost effectiveness compared to other alternatives outthere too. We have saved many hours each month by scheduling our marketing content & communications more effectively through tools such as Facebook ads etc vs doing them ourselves via traditional methods where possible instead.
