Best information sites around the web for StartUp founders

We all know that reading good content helps out our learning. It’s very easy to read and learn because most of the good content is short and pre-digested from blogger and journalists. You can also watch and listen most of the information. Hardest part is finding out what are the best sources of information. Here are a few which I read and noticed that they deliver great content for StartUp founders.
– This is the best one for reading about an all around Startup. This service was earlier called YEC (Young Entrepreneurship Community). They deliver very good information and have a good perspective. See example of newsletter here.
– Lot’s of good information. Perspective is not so young as StartUp Collective’s, but very wide nevertheless and extensively about entrepreneurship.
– Buffer is a very good tool to use and they also create great content. The point of view of their writing is technology and working culture. If you don’t like anything to read, just benchmark how they create one of the fastest growing tech StartUp.
– All these three pages create content from content marketing and social media. They all are the leading experts in their fields.
