So far i have seen many sites dedicated to worldcup including
cricinfo, cricketnext, bbc, cricketworldcup.com (official) etc etc
Site i like most with respect to
- contents
- information
- design
- performance
is BBC’s site and the worst site is world cup’s official site. I bet gupshup/kk is more informative thatn official site 
Whats your experience ? Rate your best and worst sites and post links to the other available worlcup sites.
