I've been asked to comment on my switch to Google Reader from Bloglines and compare the two.
First of all, I want to thank everyone who provided the information on exporting my subscriptions from Bloglines so they could be imported quickly without having to enter each and every one!
Google Reader appears to be delivering all my feeds. I've pretty much quit using Bloglines. There are things I like better about Bloglines. I was able to use the keystroke S to navigate from one blog feed to the next quickly. It worked even between different feed categories so that I could click on the first feed in the first category and work my way down. With Google Reader, the S keystroke doesn't work. I can still use the J keystroke to navigate down blog feeds, but the quick keystroke appears to be gone--or I haven't found it yet. If you don't mind your feeds being all scrambled in the order of receipt, you can use the J keystroke all the way down through all feeds.
I no longer have to reload Janice's page when I click to read her blog. It works like a charm in Google Reader. All of Glenn's posts are being delivered. See my original post if you don't remember the context! I compared both blogs for awhile, and the only two I seemed to be having trouble with were these two.
Some feeds arrive faster via Bloglines; others arrive faster via Google Reader. I guess it ultimately depends on which reader you like best, and if all your feeds work with your reader. I'm still maintaining feeds at both locations, but I'm generally hitting the "mark all read" at Bloglines and reading things at Google Reader.
