The answer here indicates that there is a minimum reputation threshold of 200 that one should have in a SE site for it to be eligible for sorting in the 'all sites' list of the StackExchange global box in the top left.
The comments in the answer indicate that people feel the 200 threshold is high. It would be helpful if that threshold is reduced/removed. It seems logical that I would want a SE site where I have reputation of just 6 to be listed above the site where I haven't even registered.
I propose the threshold to be reduced to 1. This would help users see all the sites they have registered to at the top of 'all sites' list and help them find and navigate to them quickly. I don't see any benefit in having the threshold at 200. However if it is reduced to 1 users get the advantage of finding and navigating to the sites they have registered to more quickly.
