i loved pbwiki until it became pbworks. man that was great. now pbworks is like a $1500 minimum commitment...
i understand that they had to pivot, but bleh.. i hate confluence, the most credible alternative.
can't use you guys because
1) no data export
2) no pricing information (I don't want a "free" product, I want to pay.)
3) no privacy policy / terms
4) no social proof of credibility (this is probably more important than any of the above)
