Naturally, mine is the SDMB, i’m interested to know what yours is.
When did “homepage” go from meaning “my own website” to “the start page in my browser”?
Google. 
Probably has something to do with the button in your browser that takes you to your homepage being labeled ‘home’. Confused me too though.
Mine’s Fujitsu. Mainly because I never bother to change mine, as I don’t see any point. So it’s the same as it was when I got the computer.
Google at home.
Company website at work. 
(The one that my primary job description is maintaining and building new features onto.)
I don’t have one set, but the things I’ll open up each time I get online are SBMD, Fark and Google News. Normally in that order 
Since it’s where I spend most of my non-email time online, MPSIMS.
blank
The browser loads up a lot faster that way.
At home, it’s my ISP’s MOTD page. (Geeky stuff like how they had to bounce a Redback in Guerneville, SBC’s activities are raising hob with DSL customers in Fremont, and they’ve turned on another gaggle of webservers in the new data center.)
At work, it’s the portal page for the primary intranet info/news/search system.
Opera (my everyday browser): home page is Google, but I have it set to open to a blank page.
Netscape: Google. I use Netscape for sites that Opera doesn’t handle well.
IE: A friend’s Web page for which I am Webmaster. I use IE to do quick checks on updates to the site.
Google’s news headlines here…
My company’s website, as I am responsible for it. Every now and then I’ll fire up the browser in the morning and it’ll time out, so I know it’s time to call the hosting service and start kicking them.
google
about:blank. My Google search is up there in the upper-right hand corner.
Straight Dope.
Another vote for about:blank.
Incidentally, does anyone know why vBulletin is adding that underscore in there? I know I’m sure not typing it in myself…
Sinfest. It’s a web comic that’s updated daily.
Safari opens to my livejournal.
IE on the PC opens to Google.
Netscape on the PC opens to www.worldofwarcraft.com
IE and Firefox on the work computer open to yahoo (not my choice, believe me)
Home - Google plus Google toolbar
Work - Google alone
Thanks for reminding me about Sinfest. I used to have it bookmarked, but lost track of it when my home hard drive crashed.
In my case the distinction is irrelevant, since both meanings refer to the same page. Actually the browser start page is a local copy of my homepage, in case the network connection is down when I start the browser. This setting also makes it easy to update my website and troubleshoot the changes before logging on to my ISP and uploading the new files.
