I'd mentioned in the blog post that out of 34 tweets that were added to the spreadsheet, only 6 of them were solid leads. But going through 34 tweets to find those 6 is a lot easier than going through hundreds of them over 8 hours.
The results of the more-filtered-list-tool would be quite interesting, though, as you'd essentially be modeling a set of "ideal leads" and determining how close/far a set of tweets are to those models. Just figuring out an "ideal lead" model for the segments you're targeting would be an interesting intellectual pursuit.
I think I might end up building this...
I have a half-baked contextual analysis implementation which I could probably spin into a high-volume twitter analysis tool. Was doing NLP analysis on unstructured data (like news articles) and extracting topics + extrapolating commonalities between sets. Could be used to pick up topics from tweets and determine if two unrelated tweets are actually talking about the same thing (without necessarily replicating the same syntax).
