Welcome to wikipedia,

Yes, this is the place to ask. Sources are essential in wikipedia world. Currently, the case is still hot and all (registered & unregistered) wikipedia users share their sources in the main page. Relying on (and respecting) a source, in a sensitive case like these protests, is important. Therefore, when editing a new info, it will be more appropriate to use the exact figures written in the sources that you intend to edit into the main page.

The sources are from Facebook, Twitter, etc. are acceptable in wikipedia. But it requires a bit more attention than the mainstream news sites (local, international; it doesn't matter) to prove the figures in those. You can see examples via http://en.wikipedia.org/wiki/2013_protests_in_Turkey#International_reaction link how to use particularly social media tools' sources in a wiki page.

And remember Wikipedia:Neutral point of view, Wikipedia:What Wikipedia is not, Wikipedia:Wikipedia is not about winning and Wikipedia:Be bold. --Toksoz (talk) 12:13, 11 June 2013 (UTC)[reply]
