Loomly is the social media calendar tool that helps marketing teams create better content, faster:
1. Create posts with a wizard-style interface.
2. Review and approve posts as a team, thanks to automated mockups.
3. Schedule, target and boost posts natively.
4. Respond to comments from your audience (fans & followers).
5. Measure your success.
Occasionally people forget to hit the Schedule button after approving a post, and a reminder for the poster/approver would be good.
This social media management site could be perfect if they fixed the cons I mentioned above.
