I'm happy to get in touch with you, and you can reach me in a variety of ways:
For non-critical information, E-Mail works best. Reach me at rixx at cutebit · de, and consider using my GPG key:
0xe1f56ce6693f9c45. I typically answer within a day or two at most, if I'm not on vacation.
My preferred messenger protocol is Jabber, where I can be reached at
firstname.lastname@example.org. I use IRC as
rixx on freenode, hackint and some other networks. If I'm online, chances are I'm reading IRC or Jabber.
If it is really urgent, you can reach me on Threema as
MXXPW35P. If it's even more urgent, you already have my phone number.
On normal weeks I can be found at shackspace, but you'd be well-advised to make sure first. ;)
