\chapter{Conclusion}

%repeat motivation
% chage is 1 of many efforts to make community better
% describe change shortly
% goal was to find out whether change improves user interaction experience for new users
% 3 criteria, sentiment, vote score, number of questions
% eval: vader -> sentiment, ITs, by looking at the 10 largest communities (list here, note so is by far the largest)

%repeat datensätze
% 10 largest se communities
% stack overflow by far the largest, >10x times math.se
% 

%repeat results
% change seems to be a success, not a one size fits all solution that works everywhere but a majority of communities benefit
% benefitters
The change introduced by the StackExchange team produced desired results in more than half of the investigated communities:
StackOverflow, AskUbuntu, ServerFault, stats.stackexchange.com, tex.stackexchange.com, and unix.stackexchange. The results of the StackOverflow community most closely resembles the expectation of improving the welcomingness. 
%in general
% first questions improved in all, followup in too in most of these communities
% sentiment raises in all except ServerFault
% vote score is does not yiel meaningful results, either completely unaffected or votescore changes drastically before or after change, only for ServerFault the time matches and there a huge spike, but it quickly returns to previous levels
% 
% no benefits/no evidence
MathOverflow, SuperUser, math.stackexchange.com, and electronics.stackexchange.com do not profit as much from the change and show not an increase but decrease or continuation in the decrease of sentiment. 
% the picture is often not clear for these communities, only one statistic improves, in contrast to the benfitting communtites where stats rise accross the board
% 1st question decrease for all communities -> bad sign
% follow up questions decrease for all except math.se
% vote score on a downward trend for all (for some even worse after)



%repeat discussion 
%
However, the falling number of questions from new contributors stabilized a bit for the math communities and the vote score increased for electronics.stackexchange.com. SuperUser saw a huge influx of new contributors shortly after the change who asked a lot of questions and dropping the sentiment and vote score value during that period.
% one day files, state communities
% seasonality, state communities, state months
% large influx, state communities, state gravity
%other odd things (peculiarities)
% - stack overflow most stable, expected as largest community, also closly matches section 3 example
% - MathOverflow sparsest
% - sentiment levels vary drastically between communities, stats has highest, tex lowest
% - same goes for vote score, MathOverflow highest by far

%closing sentences
% change worked over all, majority benefitted
% no silver bullet, no simple solution, no 1 size fits all, communities to diverse
