wikipedia.org é seguro?

Probably the best source of information you'll ever find. What a lot of people don't seem to realize is that, although Wikipedia can be edited by anyone, they do cite their sources, so any questionable facts or facts needed for, say, a research paper can always be checked with their sources for accuracy.

Online encyclopedia, but for just everything in general. Most of the time, articles are trustworthy and have sources to back it up (and articles that don't warn the user that there is little or no sources). The ability for anyone to edit pages doesn't really matter, as any edits are usually fixed within an hour to a day, max. However, the site is uncensored (for example, searching the f-word will come up with an uncensored f-word as the article name, etc.) and sometimes links to low-rated WOT sites as resources (usually dead links which link to shady sites). I use it based on the article's sources and reliability.
