What sort of errors? i mean if someone said for example Margaret T was born in 1924.. would i matter? whereas is Wikipedia said our Sun had 14 planets.... then that would matter wouldn't it?
Compared to the massive amount of info you can get, the odd innaccuracy is acceptable isn't it?
The problem is people believe it to be absolute fact without checking alternative sources. Easy to just refer to 'wiki'. It knows everything and it must be true because, well, why would it not be?
We all use it and especially so on subjects we know little about -and ther's the catch. We don't know the subject so how do we know it's correct, or not as the case may be.
In general, most of it is correct, but it does have errors and continual entries of 'misinformation'. Difficulty is knowing which.
