You're not limited to using just one website as your web browser's home page...
If you regularly visit the same set of websites each day — like Google Reader, the Winnefox Extranet, and Unshelved — you can set them all to display automagically each time you start your web browser.
Here's how to do it in Firefox 3:
1. Have all the tabs loaded you want to start each day with
2. Click Tools on the menu bar
3. Choose Options
4. Click the General tab
5. Choose "Show my home page" in the startup area
6. Click the Use Current Pages button
7. Click the OK button
You can also do this in Internet Explorer 8 and Chrome.
