I would like to know the reason behind my privileges not carrying over to other Stack Exchange accounts. I understand that reputation is an indication of how good you are at helping, etc, so it makes sense they wouldn't carry over. But when I use another Stack Exchange account, I would expect my privileges would remain, since in at least one account I have proven that I am an individual that will not abuse the system (e.g. allow me to create tags or edit a question - Stack Exchange deems me worthy of that in one account, but not another).
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
Each site in the network is different; Just because you are 'trusted' to a certain degree on Stack Overflow does not mean you should also be trusted as much on, say, Cooking. They have different standards of posting, editing, and the like. And just because you know about programming does not mean you know anything about cooking.
There is a very small association bonus, which you have achieved already. This is to get you past some of the most basic abilities. But the higher-up stuff needs you to know what you are doing on that specific site.
You do carry some of the basic privileges once you gain 200 reputation in one site. This leads to automatic 100 rep bonus on any other site you join as your accounted will be linked.
To me, it sounds just fair enough.
100 rep gives you 10 privileges:
You got that right here. You could for example be good at photography and have a deep understanding of how the community on photography.stackexchange.com works and of its standards and ways. You could be a very experienced and active user there and thus have a high rep giving you a bunch of privileges.
Now you could be joining physics.stackexchange.com. You will receive a bonus of 100 rep there to remove the new user restrictions, because you very well know how the system works, but that doesn't imply that you know how the community over there works. Thus, privileges are not transferred from one SE account to another.
