Nope. I've got Metacrawler's mail page set as my start page. I usually open IE once for that, then again to pop up the EN boards. It used to be Google, but I found I always wound up typing in the search box rather than the address bar, which was kind of annoying.
I voted no. I have my browsers (Netscape & IE) set on 'blank' as my homepage (they start faster that way ), but I do have EN World in my Personal Toolbar so it is only a short click away.
