Ist quora.com sicher?

Not a very good site to use as a source for any research, as it is completely opinion-based and has little or no moderation or internal policing, which means that vandals and scammers can easily post misleading claims, hate speech, or obscene and disgusting things, and no one even tries to moderate them. Quora itself is innocent but too vulnerable to abuse. Also requires WAY too much personal info from unsuspecting visitors to even view the site lolwut

***** is a Q&A site where a user can ask a question and others can answer the question. The site itself looks good and can provide trustworthy and good answers most of the time but the problem is the site ALWAYS requires you to sign up/logged in to use the website which is a bit annoying.

it's one of the best sites I have ever used till date. You only need to post your question, whatever it may be, then you will get the answers to it in no time. You can come to know the ideas & views of the people; know what questions are arising in their mind, and what they think the answers may be. It's really a great way of learning by asking questions,isn't it?     It's a type of group learning.

Liberal, pro Israel/feminism PROPAGANDA SITE - lots of factually wrongness and biased answers everywhere you go into details People not carrying a liberal pro Israel, pro feministic, pro gay etc attitude get banned in masses. See e.g. http://www.quora.com/How-is-Quora-biased (all Users without a name are banned (they then all receive the tag 'quora user' - or http://www.quora.com/What-are-some-highly-upvoted-answers-on-Quora-that-are-factually-incorrect-or-misleading-or-strongly-biased If accounts with unpopular opinions not get banned at least they get downvoted and therefore are collapsed. Even though I am liberal myself what I've seen on this site is just beyond acceptable for free speech. Be aware - wikipedia is absolutely excellent in comparision.

While much of this site is useful, it is difficult to give anything but a neutral rating when I have found quite a lot of the information that is pirated from other sources. The site encourages such behavior and does not provide an adequate mechanism to protect copyright. Here is an example of pirated content. See "What is the 64 bit OS statistics compare to 32 bit?" (http://www.quora.com/What-is-the-64-bit-OS-statistics-compare-to-32-bit) and compare it with the original article from which most of the text, tables and graphics have been taken without attribution or even linking to it. "32-bit and 64-bit explained" (http://www.techsupportalert.com/content/32-bit-and-64-bit-explained.htm).
