Fragen und Antworten

Fragen zur Mathe und Physik: Wolfram Alpha

Wenn es um reine Wissensfragen geht - insbesondere Fakten und mathematische Fragen - empfiehlt sich Wolfram Alpha (auch als App).

Für immer mehr Themen gibt es Hilfeplatformen, also Webseiten mit Fragen & Antworten ("Questions & Answers", Q&A) und eine virtuelle Community, wo Fragen beantwortet, diskutiert und bewertet werden. Also eine Art spontane und freiwillige Selbsthilfe-Gemeinschaft, bei der man sich nicht unbedingt kennen muss.

Technische Fragen v.a. zu Softwareprojekten: StackOverflow/StackExchange

Für technische Themen besonders bekannt sind StackOverflow und StackExchange GIS, als Sites von StackExchange. DZone, das bekannt ist für Quickguides/Referenzkarten, geht auch in Richtung Q&A.
