i guess i must have missed this announcement: Phasing out support for older browsers - Google Reader Help
sure i've been prompting to upgrade whenever i used google reader from work (yep, still on IE6 there...), but i took that as a suggestion/recommendation rather than a warning of impending cessation of support.
oh well. less distractions i suppose. though viewing it on my phone probably takes more time...
or i could start taking in my own netbook (+ byo internet connectivity) like i've seen some others in my office do!
