You’re absolutely right that shitting on people’s tools is bad.
I don’t know that i’m aware of sufficient evidence to agree that “what most of us do is [not serious enough for the performance concerns to matter].” And the claim that what most of us are doing isn’t going to be around in 5 years disagrees with my experience. Anecdotal I know, but a company a worked for until recently still maintains and adds new features to and ASP classic application.
I certainly agree that languages/frameworks persist. I work on a team as the only RoR guy with a bunch of Java developers. We have services in C# all over the place. All the more reason to cease and desist with the "mine is bigger than yours" malarkey.
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.
