Q:

Make the 'main' link more visible

Can we have a significant 'Back to Ask Ubuntu' link in meta? It took me a while to find the tiny little 'main' link.

A:

Well, usually you would get to meta only though a link directly saying "meta", thus you should be aware of the fact that you're switching sites - of course this is neither the case for everyone, nor blatantly obvious.
In my opinion, having this kind of - sorry to be blunt - "dumb-user-fallback" would be distracting. A proper explanation of meta vs main and prominent links vice-versa (i.e. right end of the menu bar contains a link to the respective other site) would be preferable.
Basically: Not just "Back to main" - embrace it directly.
