IMHO....the Cafe is a rarity on the internet. Personally, I am NOT a big fan of social media in all its forms. The best compliment I ever received was that I have a low internet footprint. The Cafe is the only place which I visit regularly and I do so for a number of reasons:
Helpful tips
Polite and friendly members.
Great access to some true masters of the program (and this compliment goes beyond the moderators who truly are "masters" but to the entire C4D eco system of tutorial and plugin developers as well as everyday users that populate the Cafe).
Great tutorials and free plugins, etc.
Tremendous and inspiring gallery.
Latest news from MAXON
It is always a positive place that stays on topic of C4D or graphics in general. The events of the outside world rarely creep into the Cafe (afaik) which makes it a nice escape to a better place.
The moderators do a masterful job of keeping conversations open and free but also respectful. I mean, we have a Houdini and Blender thread going. In that discussion, you do actually learn a lot about C4D and how it compares (which I think is positive to the C4D community). The fact that it exists at all is unique because other sites would treat any discussion of a competitor's program as apostacy and have all those involved sacked.
Access to MAXON leadership. Hopefully, they find this place as inviting as I do despite the robust dialogue that may be created over features and {...ahem...} pricing. Just remember that we all come from the same place: a love for C4D...and Redshift.
