As a student (albeit a CS major), I immediately signed up and will be using many of these services. My friends and I have been looking at creating an app and these will def get us started for no money which is huge for us (especially the ___domain name, hosting services, and private repos).
While I don't feel overwhelmed by all the services, there are some of these I couldn't see how we would immediately use such as data analytics.
I'm not sure what you're after with paid HipChat (e.g., video/screen sharing, >5GB file uploads, etc.), but Slack[1] might get it done for you for free. Probably still not ideal depending on what you want, but a potential alternative nonetheless.
I use their free plan with several projects and love it. I am just a fan of their product and think other students/up-and-coming devs would appreciate it too.
I actually filed a support ticket yesterday trying to entice them to get on the list.

I just wish HipChat was on there too :)
