I installed IE7 today and my Google Reader stopped working. I can access the reader but it won't open any of the feeds. The browser just freezes up. Oh, good old Microsoft. It made me wonder if they're up to old tricks of messing up compatibility of competing products.
Having said that, IE7 has a built in RSS Reader. I popped a few of my subscriptions in it and I have to say it's kind of slick. It displays posts beautifully and on several of my feeds I can also access comments and the blog tag list. I think I prefer it to the Google Reader. I've been using the browser all day and with the exception of this one glitch everything seems to be smooth.
