Businessweek will be integrating tweets into its comments.
Business Week is syncing the comments on its social-networking site to Twitter, making it among the first major media companies to harness the popularity of the microblogging service.
Federated Media is launching exectweets.com to help you follow the tweets from business execs. Why would you want to do that? 
AOL and Yahoo will be integrating twitter like functionality, also known as life streaming, into their web service.
The growing popularity of Twitter and Facebook’s news feed functionality has made everyone embrace life streaming — essentially a way for us to broadcast our daily digital lives via photos, videos, postings and status updates — as a way to consume information. In a matter of months, expect both Yahoo and AOL to come up with their own news feed offerings, likely to be embedded in their more popular web services. While Yahoo’s working on a life-streaming product called Yahoo Updates, AOL’s new offering, which takes a cue from Facebook Connect, is being called “Site Social” internally.Unlike Facebook or Twitter, which are taking advantage of their own social graphs, Yahoo is likely to introduce “life streaming” into its very popular email service. Other details about this service are yet to be revealed, but Yahoo has been working on making its email more social.
Similarly, AOL will leverage its instant messaging client installed base to introduce its own version of life streaming. Essentially, the new AIM client would adopt a tab-like structure where one of the tabs would be like your plain old AIM friends lists. A new tab will be used to life stream information that will come into the client from various sources.
