Ann: Executive Changes, page-5

I haven't looked at the broader market for some time but my understanding is that Manalto was built with enterprise/franchise groups etc that have a large social presence. One of their core features is the geo-targeting and scheduling tool that lets you post across thousands of profiles in one hit. Hootsuite was primarily a consumer/small business tool but I understand that they have tried to move into the enterprise space.

Price wise they work on a per unit/page model. Most other platforms are per seat.

Cheers
