Trulia widget promotes localized listings on Topix

Listing aggregator says it's now partnering with 50,000 sites

Listings aggregator Trulia has developed another widget the company says will help it tap into the "long tail" of visitors to hyperlocal sites by promoting listings tailored to geographic location.

Trulia’s new dynamic widget is scheduled to launch today on Topix, a Web "news community" that rounds up links to news stories and blogs, and helps users find and discuss them at the local level.
