Why you should idly browse Wikipedia

I've seen it said that one should not use Wikipedia because at any given moment, a page might be wrong. But what's that error rate, versus the error rate of your own memory of miscellaneous not-significant-to-you-at-the-time information?

If the latter is ≥ the former, then even if Wikipedia is worthless for reliable information, it is still then useful to browse it randomly, or in a topic area of slight interest, because afterward you have increased your total knowledge while not increasing your error rate per fact.
