netgister
NetGister monitors what people are saying across multiple social platforms. 
If you interested in being notified immediately when people are discussing certain topics of interest to you then customized “mash ups” are one of the best aggregation techniques available. Mash Ups can produce tailored results from data sources that can otherwise be lost when using conventional search engines. By combining our custom software with robust aggregation engines such as Yahoo Pipes using simple commands can be combined together to create output that meets your needs:
- combine many feeds into one, then sort, filter and translate it.
- geocode your favorite feeds and browse the items on an interactive map.
- power widgets/badges on your web site.
- grab the output of any Pipes as RSS, JSON, KML, and other formats.
