Ask HN: Slinkset or not?

What could be the potential disadvantages of choosing Slinkset to build a commercial consumer product...

I've tried Pligg - It attracts too much SPAM and i couldn't figure a way to avoid it...

I like Slinkset but not sure if its the right way to go, given that it is hosted and not completely flexible...

Would you try build a business that's too dependent on a provider like Slinkset?
