Typo: 'conneciton' -> 'connection'.

I'd like to reword this slightly, if you don't mind:

choose_pod_exp: "Find a pod that suits you. You might prefer a smaller pod, one which is allows cross-posting to external services (such as Twitter), one based near you, or one based in a country that you know has good data security policies... The choice is yours! You can even %{host_yourself_link} if you have some sysadmin skills." host_yourself: "host a pod yourself"

Thanks for your review Goob, I applied your suggested changes.
