I think something ought to be done about the appearance of the default footer.
I understand the justification of all those logos, but they are so numerous and, with the addition of rss buttons, they become clearly a nuisance.
It is just compulsory time-consuming work for the consciencious webmaster to edit the logo. Those who can't do that will just remove bot or even change cms.
There are many cms who have elegant discreet opensource buttons. The tiki bot bar is close to aesthetic provocation.
