Not to be outdone by Google, Yahoo also added real-time Twitter results for "buzzing" keyword phrases. I tried to replicate any results on Yahoo, but I was not yet able to see them. Maybe it is still rolling out.
The industry is discussing the Yahoo roll out at WebmasterWorld.
Meanwhile, sometime mid-afternoon yesterday, the real time results Google previewed a couple days ago, went live in the main Google search results. SEOs and Webmasters are now playing with it, looking for ways to
exploit take advantage of it. There is discussion on it going live at WebmasterWorld.
