I haven't used tag clouds myself, but at a superficial glance, the
del.icio.us usage in your example seems accessible enough to me: they offer
the option of sorting the list alphabetically (default) or "by size". If
you sort the list of tags by size, then a non-visual user agent will be able
to extract the same information that is currently conveyed by size/colour to
other users. Perhaps the tag list should be marked up as a list, rather
than a series of anchor hrefs, but in general, the information provided by
the tag cloud is still available to non-visual and/or colour-blind users.
