Wow, you think they would have left some part of the old logo during the transition.
To a new visitor to the moniker site what impression do you think they will have when they see the name/logo
"low budget no logo...must be a parking site"
"no logo? - maybe its a start up company"
"they cheaped out on a good logo design...must be an affiliate or reseller site"
Personaly when i see some branding and effort into a logo or design it adds a little more creditability to the company/site.
