Developers’ replies are the most important here and I’m not one of them, anyway here’s what I try to do:
- talk around about the modules themselves, but even better:
- make good free communication about them (if you have a relevant social media audience, post when your audience is active. Choose the most appropriate link about those modules, check that it works, and include it in your post. Include a nice picture. Describe why you like the modules. Amplify the developer social media activity if they have one, etc)
- provide useful, constructive feedback to the developers. If you report bugs, do it the right way and put some effort in it
(late edit: I moved this topic to #Rack since it may concern any generic Rack user)
