I do a quick scan for tweets with high engagement %. Typically >8.
Then turn into an email, blog post. Subject line, ad or whatever.

I use Twittonomy. Useful and not well known. Scans any profile for most likes and retweeted.
GREAT for ad copy and to have a general idea of what other audiences dig.
