There are many collectors across the whole spectrum but I can understand why you said that. The largest group of visitors are the more active on the net and this tends to be those that are collecting the major interests of the present age. The classical collecting areas of drinking glasses and cut glasses have a low profile these days but there does seem to be a swing in those directions starting up. I for one would welcome a fresh look at the earlier periods of glass and the only way that will happen is by questions being raised. We also seem to lack collectors of flat glass and bottles, although they probably lurk quietly in the background.
