I visit Wikipedia virtually a few times a day. It is like an addiction. Even when I search something in Google, I always add the word "wiki" to first see if Wikipedia says anything about it. But of course I go ahead and check out other sites as well...I am aware of the problems associated with Wikipedia but despite that I still find Wikipedia to be the most useful and efficient encyclopedia on the internet.
I am so grateful for the existence of Wikipedia. One can have access to almost any information, usually in its most digestible and terse form.
