Buy a domain and hosting for a year  - namecheap.com accepts BTC, and they do domains + hosting, though for the latter there might be some other, cheaper hosts.

Build a website, a blog, a personal gallery, whatever. You probably won't make any money off of it, but hey, having a place online to call your own is neat. (Source: I have a place online I call my own )

If you want, you can do something for the community using that website, and ask for BTC tips. You never know!
