I've been trying to figure out a way to measure engagement via the latest activity rss feed. I've been playing with google reader with some success but find either my knowledge or the functionality lacking. What I do it star the activity I'm most interested in then manual add it up. The process stinks.
I'd like an automated process that sums up certain phrases that appears in the feed in given time periods and also give me totals.
So far example:
I'd like to see how many blog posts were added in the last seven days, and if I wanted by member, a, b, and c.
I'd also like to see how many members left comments over the last month or replied to a forum discussion or group discussion.
Any rss ninjas out there or someone else with a good idea?
