How to do organize papers, urls and other TCS related resources? This question is a try of making 
Do you use any article organizers? question suitable for TCS (as suggested in meta answer https://cstheory.meta.stackexchange.com/a/359/6133 )

Question similar -> about organizers, but ...

What organizer do you use, know that are possible to handle TCS related meta-information ?

We organize our knowledge in many ways.


Some of them are hierarchical, as complexity zoo.
Others more like graph -> let's take algorithms as vertices and how they are related with each other as edges
As another extreme, some knowledge we organize like sets and think about it in terms of sets intersections - to be more specific conjunction of criteria, just like flat tags.


I would love to see tool that combines many approaches and enables collaboration between researches, even better, if between strangers (possibly with crowdsourcing).

Above might relate to Academia in general.

What I mean is that TCS people have more CS skills, knowledge and are able to apply it in organizing their own information. 

I believe our approach in organizing information is different, partially because we use concepts of graphs, sets, ontology in our job, so they are natural to us and we are able to handle complex models of organizing information, which might use or even might all of mentioned. On the other hand, people from non scientific fields (especially not math related), might have problems with using such models and I believe that's the reason why almost all tools have so much simplified models.

I use "hacks", "tips&amp;tricks" to extend them, but it's not comfortable and not build-in. I even run sometimes analysis tools on my own collections of data - but again, in hacky, why. I would love to see really flexible tools, suitable for CS / TCS people.
I am old school and just use files and folders to organize everything. I have it in Dropbox and I share it with my professors or other students. I think using files and folders although it isn't very fancy but it works well. I have tried special organizers but never used them.
