Interesting people, competitors, OSS projects, commercial libraries, third-party services, design and marketing ideas, notes on investors, potential future use cases -- what do you use to organize it all?
I am not all that diligent, but I just use Instapaper. Save all the relevant links (the link itself will say to me if it is a competitor that I must keep an eye, an interesting prospect, a tip on sales, copywriting advice, a SaaS i will want to use in the future).
At the most I separate into two generic folders: code and business.
Paper is my first layer of organization. Just about everything that crosses my mind winds up in Moleskine notebooks (large size, unlined). From there, it may land in the cloud somewhere.
