Background
I'm a one man shop (a micro-ISV). A week after putting my product online I get a mail from one of my customers about a bug. It was an obvious fix and I fixed it in 5 minutes but I realize that the reason why the bug was reported so late is because the only contact I have with my users is through mail.
I feel I need something more but I have difficult time finding the right solution.
I was checking out some solutions, but I would like some feedback from the community
Question
What do you use for a micro-ISV (both online and built into software) when you want to give good quality service and support to your clients?
