For the record, it's running *exit* relays at home that is not
recommended. Running non-exit relays at home is typically fine -- the
most likely problems are that some overzealous blacklist will put your
IP address on their list, making some websites not work so well for you
if you also use that IP address for your own traffic. Some of these
overzealous blacklists are just being stupid, because they don't
understand about exit policies:
https://www.torproject.org/docs/faq#ExitPolicies
but others of them are intentionally trying to harm people who are
trying to support Tor:

But back to the original thread here: some residential ISPs filter
incoming port 80 for all of their customers, to make it hard for you to
run a website at home unless you upgrade to the version of their service
with the word 'business' in its name. So if 80 isn't working, and you
can't figure out why, one of your debugging steps should be "see if a
different port works better".
