The raw experimental data was gathered and analyzed using statistical methods, developed initially for Twitter. Based on them audience was classified into categories then main attributes of updates was carefully studied to develop derived indicators which can show not only audience quality, but also information coverage and partly influence (e.g. growth of authority and so on) and demonstrated using graphical charts. Indicators were generalized into formulae-so was built a base to further studies on Facebook account activity. Directions of future work are also listed in conclusion.
