A twitter is worth a thousand contact us forms
I buy a lot of apps. I believe good software is worth paying for. If a developer(s) has made your life easier, ze deserves a reward for the effort.
I imagine alcoholics also say bartenders deserve a drink to be ordered from them if a good spirit is featured in the shelf.
Regardless of the justification for my victimless digital addiction, I do have a very a simple rule to indulge in new apps by unknown developers: they must have a twitter account.
Saying that you would love to hear from me and just having a Contact Us form, tells me you really don’t.
I understand that managing a twitter account1 can be a pain, but it’s exactly the sort of pain that sends the right signal about your app: somebody is standing by it.
