Is there something I'm not getting?
I've set up RSS feeds for some of my often visited sites, and, yeah, I get that now I can go to Google Reader and see if there's new postings from there but it never seemed that difficult or time consuming to check out my favorite sites using the favorites function. Plus, blog content as displayed at Google Reader seems stripped of context. Sure, the entries now "come to me" but considering the whole concept of ambient findability, isn't everything, everywhere, immediately accessible anyway? I.e., I'm already plugged into the hive brain by virtue of being online. And I still have to go to the Google Reader site.
Admittedly, I'm not a hardcore user. There's only a handful of sites to which I'm truly devoted. And I suppose I could see how this could be very useful to someone whose job requires them to be monitoring a large number of sites. So that English teacher who gives her students the assignment of starting a blog and then needs to be checking all of them--for her, a good thing indeed.
For me, a little baffling. But I will keep fooling around with it and update here if my initial impression changes.
