How do you recommend keeping bookmarks as a team or company?

Hi Florian, this is a great question and I'd like to add a couple of points to it.

When a team reaches 20+ people, we start feeling like we are losing alignment. And it is true. It's hard to expand a team and see everybody thinking equally after that point. We have learned that you should be looking out for 3 types of knowledge sharing:

1. Inspiration (or information drops) - these are the links and files we stumble upon every day and think like “hum.. my team would surely like to read this, let me share it with them”. This may not have an specific goal or might not even be related to your field/industry. The value of these little nuggets is that they might complement someone else's creative process and inspire them to do things you never predicted. So we share. This is mostly done by Slack or E-mail today (and very inefficiently).
2. Liquid Knowledge - these are the things we are learning about right now. They are the topics we are interested about, probably related with our next goals and milestones. Let's say you work on a startup and you are changing your sales model from field sales to inside sales. Well, there is a lot of new stuff to learn and, as your team researches and shares, you start to get a better understanding on the topic. You start throwing out the bad stuff, keeping the good stuff, putting in order, etc. You end up building some artifact from this (presentation, google doc, etc) and this becomes useful for more people. You are still growing your understanding of the topic, but it's becoming more familiar.
3. Solid Knowledge - this is basically composed of things like best practices and training materials. Think about this as the things that the group already knows and considers to be right. Product training materials, employee onboarding, “how we do things here”, etc.

So, as you mature your company's knowledge processes, look out for ways to make this 3 types of sharing better (and integrated if you can).

Disclaimer: I am the CEO of Skore, a platform that does just that. :)

Tools I like to use:
Diigo - Better reading and research with annotation, highlighter, sticky notes, archiving, bookmarking & more.

To do list and task manager. Free, easy, online and mobile: Todoist (because of it’s incredibly easy way it saves webpages in lists)

Papaly.com - personalized Social Bookmarking
Nice way the boards categorize links - boards can be shared

Thebrain.com mind Mapping Software, Brainstorming, GTD and Knowledgebase Software -> Complex, yet versatile for links

Evernote.com
Notebooks can be shared

You could maybe create a setup with these tools…

I was recently talking to these good people at Smarp. Looks like it’s just the thing you might be looking for. Please do check them out since they make it easy for you to share, curate, and bring in team advocacy.

Sorry, Answer is too late.
