My first experience setting up a server for an open source project was setting up Wallabag (Pocket, Instapaper alternative). The quality of that project inspired me to find other projects to setup and I eventually set up this Mastodon server. I wrote up a little tutorial if any one else is interested in setting up Wallabag
