Twitter user types and their prevailing communities.

The top 890 users from the major communities, ranked by the retweet h-index, are classified into different types. When possible (in over 72% of the cases) the prevailing community across the five timepoints is determined. The rest of the users shift between different communities through time. There is an interesting transition community Left→SDS that corresponds to the government transition from the left-wing to the right-wing, and consists mostly of the governmental institutions.
