Like millions more, I guess, I use Google Reader for my RSS feeds and I've always found it perfectly satisfactory. However, hackles are being raised by Google's decision to allow the links you have shared with friends or family to be available to anyone. Now, this doesn't bother me, because I rarely share links, in fact, I think I've only done it once, but others might well be put off.
It doesn't stop there: if you are a GTalk user for chat, then the links will also be shared with anyone with whom you have chatted - again, I don't use GTalk, so it doesn't affect me.
