Interesting that Twitter posts will soon be searchable on Google and Bing (details here). I like that the article covering that development was titled drinking from the firehose.
With the web becoming more realtime, it also potentially becomes more distracting. For example, you could read blogs for the most recent information, or you could read Peter Drucker or Benjamin Graham for a timeless perspective on business and investing respectively. I would argue that focusing on the important rather than the recent is far more effective. Yet tools increasingly drive us towards what is new, rather than what is good.
