As someone who (a) has tried most help desk services and (b) owns a company that has a really strong reputation for good customer support, I've come to the following conclusions:<p>1. No tool/service has every feature we need and we always end up compromising somewhere.<p>2. I personally think most of them are over-priced, especially for new/small startups.<p>We used an in-house Rails app for support for a long time (it's open-sourced here: <a href="https://github.com/bigfolio/big-help/" rel="nofollow">https://github.com/bigfolio/big-help/</a>) and now we use ZenDesk. This tool looks cool but they all sort of lock you in because my support staff doesn't feel like re-writing/pasting FAQs, canned responses, etc.<p>Overall, I just feel like this is a weird space that has no clear winner. I don't see anything compelling with UserVoice that would get me to switch. I think there's clearly room for a competitor with better pricing though. I almost feel like this is an ideal space for a good open-source project (so firms can customize and deploy) that has a commercial hosting side (ala WordPress).
