I've used Ruby and Python and PHP for web related projects. I've used C for low level programming, Linux modules and SCADA programming running on QNX. So I guess I like pretty high level and low level programming
Well, there are a number of web frameworks being worked on, maybe checking them out and helping out would be a good idea? https://github.com/iron/iron was on HN asking for help the other day.
Well, like any turing-complete language, technically anything, though Rust tends to be lower-level than most.
What kinds of programming do you like to do?
