Great site for having students calculate some proportions and develop proportional reasoning from a variety of contexts. Based in KY but can still connect to many students. 

Killing two birds with one stone. Here are some interesting facts about social networking and use among 35-54 yo age group growing by 60% recently according to Forrester. Also, if you are looking for a read-aloud to do with math students, here's a great example to use with them. The topic is social media, the content is proportional reasoning, data analysis, and interpreting real-world data. For example if usage among 35-54 yos has grown by 60% what does that mean among the sample of 4500, what does that mean among the sample of the US population, if previous usage was 15% of that age group, what percentage of that age group now use it? Etc. Good math/science reading is as close as your local USA Today/Yahoo homepage/iGoogle/news RSS
