Ask HN: What user support/feedback system do you use?

I'm developing a web service that can capture a snapshot of a web page when a user is filling in a support/feedback form. The idea being that it's much easier to help someone when you can see exactly what their page looked like. (Even if they are logged into some non-public app page that uses lots of ajax.)

So far my service is capturing the snapshot and returning a generated URL for it. You can log in to browse the snapshots (along with date, user-agent info, etc).

Should I enhance my service into a fully fledged support system, like Zendesk for example? Or are you already happy with your user support solution and would just like a simple way to integrate something like my service? I'm trying to gauge what I need for an MVP.

What support systems are you currently using? Do you prefer to roll your own?

Thanks for any feedback you can provide.
