By now, most Googlemail accounts have probably had the new “Buzz” feature made available. This feeds snippets from people you know, such as their tweets or blog articles they have marked for sharing, and allows you to make comments on them.
To some extent that is a great idea, facilitating contact and conversation. However it does seem like a rather daunting stream. My particular concern is duplication of items I have already seen elsewhere. Seeing them once is interesting but having them pop up again is redundant. Also, it risks conversation about the points raised being lost. It aggregates blips of information but disassociates responses from the original source.
So far, my take on it is interesting but not entirely welcome.
