Once in awhile I check my Google Reader Trends (found in the top left of your GR, under "Your Stuff") just to see what my habits are (and how I can synch or shortcut).
Here's a screen shot from this morning:
So, in a 30-day period I "read" 18,402 items. Wow! But since I know my "Skim, Scan, and Save (then Share)" habits – I know this is a misnumber:-). I skip over at least 400 of those 613 items.
I like the average of 5.7 per day sharing (either on Google Reader or via email). If it climbs or gets concentrated in one area, I'll wonder if I'm creating too much noise.
The "starred" items has me concerned (an average of 30+ per day get saved in my Google Reader starred items). I need to improve my filtering.
When I add the 188 items clicked, that brings my activity level on RSS feed items up to 42 per day (and that doesn't include the scanning past those other items.
Time to prune the RSS bush.
The great thing about Trends is it also shows you specifically which of your subscriptions you read most, which ones you star most, and the number of items each site publishes a day (Mashable averages 19.5 — but it's all so good)
Maybe it's time to really skeleton my RSS feeds and rely more on my Twitter + Yahoo pipes. I'll let ya know how this goes…
and please, let me know how you scale back on your infosumption to make it digestable.
