First of all, congrats on the 2 year mark.
For my part, I'm a seventh-day adventist (I know that makes me unpopular on some forums) and we don't use any kinds of drugs or alcohol. I've known people getting their lifes destroyed by alcohol abuse and I guess we can do better with our lifes. My cup is allways filled with tea (when cold) or orange/lemon juice, but ultimately I believe the beverage won't make you a better developer (so it seems like a joke when reading some posts by a developer being "drunk" while coding).
I agree, it won't make you a better dev. I for one have noticed that my mental acuity is almost doubled since I stopped booze and cigs.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
