The reliability of the source is relatively less important. The only real problem occurs when the "source" is, in fact, another entity like Wikipedia--one in which the identity and credentials of the contributor are not easy to assess.
Or an average nineteenth century historian.
The 'line of questioning' that just emphasises sources is always going to be rather limited. One can easily write an article that is accurately sourced and fails NPOV; or may have to write an article that uses biased sources and yet attempts NPOV. It may actually be harder in the former case to bring an article in conformity with NPOV.
But I think 'reliability of sources' will be an ongoing issue. Particularly as blogs develop.
