- Don't show any tweets on first poll after authenticating.
- Could do something like not show tweets older than our last poll time. At startup we set last poll time to 'now'. Each tweet has a created_at that we can parse with format %a %b %d %T %z %Y. If we did this then we could drop the ignore_tweets logic as we could use the same logic. This would improve new follow behaviour as well as it would mean you could follow accounts via the website.
