I agree that the lack of search is a bummer, but you are wrong about being able to add comments. This comment was added by clicking the 'Add Comment' at the bottom of your entry.
The lack of search really is retarded. It was so obvious that google reader would have a search that I didnt even think of checking for that before adding my feeds to it... now the only reason I am not switching back away from it is laziness! Another killer is that the "Read" status keeps resetting itself, no matter how many time I click the "Mark all as read" button - so much for sharing that between machines. It is also fairly slow though I guess that part's a given with a web app.
Hi. My reason to really like Google Reader (and recommending it to everyone I know) is that it follows me wherever there's a browser - the quintessential quality of any browser based application - but in addition it even goes on my (any) mobile WAP-phone so that I'm _always_ updated with the latest from the ISerializable blog :)
Per - I agree...having my feeds up-to-date wherever I am has trumped functionality of a rich client. It's very nice, indeed.
