If you just want to give a quick feedback, please message me on twitter @minddust.
This might be the fastest way to get in contact.
If there is something more personal you want to tell me or your message exceeds the 140 character limit, feel free to write me an email at firstname.lastname@example.org.
This might be a little bit slower, but I'll try to check them every other day.
By far the slowest way to get in touch is by old school mail (German law requires me to offer you this information).
Nonetheless if you are really happy with this service and want to send me a postcard, here you go:Stephan Groß
