The year Twitter died: a special series from The Verge
(www.theverge.com)
This is a most excellent place for technology news and articles.
Personally, I think giving a voice to the voiceless is important and twitter's role in many of the protests listed in the wikipedia links I assume you ignored have been incredibly important. Especially as it gives a venue to convey information that news outlets might shy away from for a range of reasons.
If supporting civil disobedience and a way for people to rapidly communicate and coordinate searches in times of emergencies is childish then I hope to never "grow up"/
