“BTW, this is also why the river of news approach doesn’t work for everyone. If you’re subscribed solely to feeds from popular blogs and web sites, a river of news is ideal – you get a flow of information that you can scan for stuff that looks interesting. If you miss a story, no big deal – it’ll float by later if it’s important. But if you’re also subscribed to feeds critical to your business, this approach is unacceptable. You don’t want a flow of uncategorized, unprioritized information that combines articles from Boing Boing with items from your company’s internal feeds. You need separation between the stuff you read for fun and the stuff you read because it’s critical to your job.”
