You don't need to tell me about the usefulness of printed sources! It would be a mistake, however, to underestimate the potential importance of material available hidden away in old, sometimes long, threads; some of which (many of Bruce Olson's contributions, for example) simply is not available in printed sources, or supercedes them.

That said, I daresay that I may have been a little over-sweeping in my original remark, though I do feel that web tv imposes considerable handicaps on anyone wishing to use the web for more than occasional dabbling, and that it is not always pracical to set the pace according to the slowest runner.
