You haven't been able to find any other sites focusing on finance or sports on the internet? To be clear, yahoo does a decent job curating finance and sports sections, but it is extremely trivial to find sites similar to Yahoo. Here are a few, I found:
Finance:
========
Marketwatch[0], is very similar to yahoo finance. Owned by WSJ and Dow Jones.
Google Finance[1] is like Yahoo! finance, only done by google.
MSN Money[2] almost the exact same thing as Yahoo.
Then you have your more niche honorable mentions like motley fool, seekingalpha, zerohedge, etc.
SPORTS:
=======
Without repeating Google and Microsoft offerings, there is of course:
ESPN which is the second largest sports news provider, also they have a tv network about sports. They sports fairly hard.[3]
Bleecher Report is not to be out sportsed, sort of a hipster pitchfork media type sports player.[4]
CBS Sports[5]
NBC SPorts[6] This, and the preceding offering are large entrenched media rent collectors, which is similar to yahoo, except that they are profitable.
So, in finality, I find that statement absurd, but I am glad you enjoy yahoo. I am rooting for it as it is an under dog for sure.
