I'm looking for a good source to scrape for social media / trend info.

So far I've found a couple of contenders:

1. http://www.socialmention.com/api/ - (Free up to 100 searches, small operation)

2. http://www.viralheat.com (Free currently, looks like a bigger more competent outfit)

Does anyone else have any others they know about and would recommend? What I'm looking for primarily is a decent range of info and signs of longevity. I don't want to pay someone to integrate the API and then have to do it again in 6 months if the site vanishes.

Cheers, JJ
