I'm not a big fan of sound on websites, but talking heads with sound? OK, now you have my attention. SitePal apparently delivers just that, with somewhat freakish characters that appear to be saying what is actually being said. As the site says, for as little as $9.95 a month, you can have a SitePal on YOUR very own site. It appears the company also makes custom Pals, as I found one for Santa Claus.
Maybe you don't remember Max Headroom, the music-channel announcer for a late '80s sitcom. The shows weren't that great (which obviously spelled the demise for Headroom), but his legacy still lives. Maybe SitePal could revive Headroom and throw him in a blog somewhere.
