The very first thing I do when I go online is to check my email, so my home page is set for the login page of the webmail service I use (rocketscientists.ca): RocketScientists.ca Webmail After that, I check delicious, and from there I can get to DP (it is one of my bookmarks on delicious).
Mine's set to Google. It's also one of the first few pages that I browse everyday, especially when I need to do research for work.
I use firefox and have it set to the UK Google as use it as a research tool all the time. I also have chrome and that is set to the BBC uk site so I can keep up with the latest news and sport.
None, I use the speed dial page for opera and chrome because I want to open quite a lot of tabs every morning
I am using Opera. no home page, speed dial page coming first. in speed dial page - Google, orkut, gmail,DP,paypal, yahoo,and three own sites.
