Ask.com launched a new service that uses its Bloglines service to assist users in finding blog topics that the mainstream media may be missing. The approach is different from other services, which work like traditional search engines, and will help to limit the problem of blog spam, which is becoming increasingly common, the company says.

Users will be able to save searches and share results as RSS feeds. They would also be able to post searches to sites like Bloglines or Digg. As well as appearing on Ask.com, the company plans to integrate the new technologies into Bloglines as well. The new option is available immediately from the Ask.com homepage.
