For DIY quantification, create a spreadsheet of userids, threads and manually tagged perspectives from your favorite social network or discussion forum. Then apply open-source tools for social network graph analysis of node interactions. With this data, apply exclusion filters to targeted clusters of userids, then re-read the "mass opinion". Palantir has proprietary software for network influence analysis, but many algorithms and OSS tools are available from academia.
