Quite annoyed that Google's g+ in past month () assume your window size must be quite wide.
Meaning: the page is designed to assume a minimal display width as optimal.
For example, if your window is not that wide, part of page on the right side won't show. A horizontal scrollbar shows up. You have to use that.
Here's some minimal sizes for each site.
Facebook = 1014
apple.com = 1014
google.com = 1014
microsoft.com = 1000
Yahoo! = 1014
amazon = 1033
Twitter = 900 (mininum); (990 to show all items in nav bar)
Gmail = 994 (mininum); 1290 (no horizontal scroll bar)
g+ = 994 (mininum). 1080 for nav bar to float.
Google Reader = 952
DISQUS = 1180
The above are tested with web browsers on a PC, running Windows 7.
