Hi,
I don't have a simple solution that I could suggest to you now. But I have a question for you: if you found a product, that would do that for you (a computer software, that would get all the information/updates from different websites, combine it in one place and optimize for you to absorb) would you buy it?

I am a data analyst and my specialty is text analytics. I can take large amounts of text and find some meaning in it. For example, get a set of law documents and programmatically analyze it to build an argument; or I can take pictures of food from someone's instagram account and predict person's weight in 2020. So, I have an idea how to solve a problem like yours.

What I can recommend for you right now, is a VA (virtual assistant). I have one myself. She takes care of the information flow. Reading, summarizing, writing lists and notes, making charts, etc. It isn't very expensive, and you can hire some great, highly educated people that are undervalued by an average employer (stay-home moms, fresh grads, people living in remote locations, etc).
