So as of the more recent commits, the profile pages have been becoming more and more complex, and will have even more new features that should ease your overall experience with the website.
However, I've recently been looking at this Youtube clone called vidlii, a service meant to capture the old Youtube. In that service, you can create your own theme for display in your profile. I, however, want to take a different approach and try something different.

Basically, lets say I have the theme "yellow" and you have the theme "blue" (yes, I'm unoriginal), and you access my profile.
Instead of seeing blue, you will now see "yellow".

This is something I've been debating over for a long time, and rather than let my dumb mind take control of everything (see: Randomised User ID's), I'll let the community decide what we should do.

This time, however, its going by the poll. I'm not taking an exception from anyone. If you didn't vote on the poll, and then you complain that you dislike the change, well you should've voted. The only reason why I'm mentioning this is because it happened with 2 previous "members" of the community which is now long gone.

Poll ends on May 17th.

So I was actually on vacation so I didn't end it at 5/17. So I'll do so today.

Poll results.

5 users voted that the theme should change based of the other user's profile to the other profiles theme.
0 users voted that the theme should not be changed based of the other user's profile.
1 user voted that we should have custom themes like Vidlii/Old YouTube.

I've decided to go with the "5" users and have the theme change based of the other user's profile. If users really want, I can make an option to turn it off.
