My tiny involvement (hosting/updating i58.tf alongside vibhavp who dev'd it in less than three weeks) made me feel so welcome at i58 and helped me start a few conversations with the awesome people present at the event. It was an experience I did not expect and will definitely not forget.
This is why I'd also like to offer my help.
My day job is programming, mostly back-end web, natural language processing, also dabble in front-end when it's needed. I prefer using python.org, haskell.org and elm-lang.org when starting new projects, but I'm able to work with php/cpp/java/js given enough time.
I'm also knowledgeable using Linux/UNIX systems, hosting TF2/source/mumble servers, networking computers, all of it self-taught.
I used to write a lot during high school, mostly short stories but also papers although I am definitely rusty (as you can see from the i58.tf landing page's text contents).
I'd love to try to learn stream production and camerawork, but my current internet connection won't allow me to do 720p60fps.
I'd be able to dedicate a half-dozen hours of work per week, or so.
I'll definitely be working on internet coverage for the next big TF2 events either way.
