Do You Find Some Wrong Info In Wiki?

I sometimes do. But, that is just what happens sometimes. More often than not, it is quite accurate. So, I do not worry about it. Or, I correct it if I feel the need to. :)

yeah there is slight ambiguity in the case of some topics.. because it is an open forum where everybody can share the knowledge.. there is scope for wrong info.. but if some other user identifies the wrong info then he can start a discussion highlighting the false scope of that info... and when such a discussion is going on then wikipedia labels that particular section of info as "being under review" or that "the neutrality of the info is under discussion".. so u can cross check that particular section of info

I have not yet.It is very useful site that all I can say.
