I quite like the last sentence:
"In a post-Wikiepdia [sic] universe, in which the quantity of
information may too easily be conflated for its quality, such mistakes
may be all the easier to succumb to."
I think that's an excellent point. People using Wikipedia need to know
what they are using - a fantastic source for wide ranging information,
but not a specialist resource that can be trusted to have everything
you need to know about a given subject (and have it it correct). There
must be better ways to research politicians (political who's whos,
looking at actual polls, reading transcripts of their actual speeches,
reading manifestos, etc.) than looking them up in a general
encyclopaedia.
