The Wall Street Journal digital blog is reporting that Twitter is talking to Google and Microsoft about licensing the live Twitter feed to appear in Google search and Microsoft's new search engine Bing.

This would be a very good move for Twitter, writes ChannelWeb's Brian Kraemer, who said the three-year-old Twitter has been struggling to monetize its popular and growing social network, as Facebook is increasingly showing social networks can make money from applications and behavioral advertising.

Small businesses and entrepreneurs are taking advantage of the marketing possibilities on social networks, while search engine optimization (SEO) techniques allow marketers to get their blogs - and soon their Tweets - ranked and indexed in search engines like Google and Bing.

Kraemer writes for ChannelWeb that Twitter's only Achilles heel amidst its astonishing growth is its struggles to keep up and running at all times. Twitter has suffered from many "fail whales" - the image that shows up when users can't access the service - while hackers have targeted Twitter with spam and denial-of-service attacks.
