I agree it's unusual.

What links did I post on reddit that would be inappropriate for the 
charter of that site?

I'd find that difficult to argue. Consider:

http://forum.dlang.org/thread/l37h5s$2gd8$1@digitalmars.com?page=3#post-wllaccthfrnvquuhsbsr:40forum.dlang.org

It was a factual, undeniable piece of good news: some nontrivial D code 
was starting daily use at Facebook. There was no sensationalizing to 
complain about. Yet there had to be one smartaleck comment, and guess 
who it came from. Just browse through your own posting history. Making 
one's name a great predictor (NLP machine learning algos for sentiment 
analysis would love it) for snarky comments, facts be damned, is hardly 
being neutral.

I appreciate your very strong contributions to the bug reports and 
associated discussions. It seems you are worried we're too busy keeping 
in denial about our shortcomings and feel the urge to keep us grounded 
every so often. Worry not. There is time to focus, and there is time to 
chillax.

I agree we should fix problems that prevent maximum performance from 
being achieved simply and easily.
