If at some point you feel compelled to revoke your "fan" status and remove Tridion-related posts, you might consider stopping participation in Tridion Stack Exchange.
Considering the fact that former "Tridionauts" still participate in the site and sometimes make their way back to the profession, I'd say current and former community members should participate at a level that works for them.
This Q&A site is wide open, so there's no harm in "competition" joining the site and any off-topic discussions and comments will be downvoted anyway. :-)
In a way, it's actually good for the community, software, and StackExchange to offer a Q&A experience that's engaging enough to keep former practitioners involved. At the very least, you might add comments or clarification when we start misquoting your blog or your old forum posts. ;-)
