I'd appreciate your help and advice selecting a social commenting/sign-in solution for a news site. What do you think are the most important selection criteria? How much should it cost? I have looked at a number of vendors in the space such as livefyre, Disqus, Gigya, janrain. ONeall and Lanoba. I have used a couple of these tools previously but would be really interested to hear what members views are from a customer perspective. Are you happy with your current solution? What selection criteria did you use? Any help would be greatly appreciated.
