Merlin Mann (through his awesome 43Folders blog) just posted some tips to help decrease distractions via email. Glaringly obvious stuff. But, stuff that I wasn't really thinking about.
So I just did something radical. I quit both Mail and Blogbridge. I'll fire them up a couple/few times a day, but they don't need to be open all of the time, just begging me to pay attention to the new, urgent, and interesting stuff that might be waiting for me.
Next up - updating/maintaining my kGTD über-ToDo list.
And, yes, I'm aware of the irony of responding to an always-on RSS feed that is suggesting that things don't need to be always-on...
