Amid the rise of Facebook and Twitter, Yahoo (NSDQ: YHOO) seems in some ways like yesterday’s news. But does the portal have more sway than people think? New data from the commenting platform Echo suggests that when given a choice more people log in to comment with their Yahoo accounts than with Google (NSDQ: GOOG), Facebook or Twitter.

The data, which covers about three months’ worth of login information, includes only the top 10 publishers that use Echo, like CNET, Slate and Technorati. And, Echo, of course, is eager to circulate it because its commenting system—unlike those of some of its rivals—lets users log-in with their Yahoo IDs. Nevertheless, it may serve as a reminder that despite all the buzz around newer communication tools, mainstream audiences tend to be slower to migrate over.
