This might be fairly simple, but I can't find a good solution - A replacement for Google Groups.

More specifically, a better UI to use Mailing Lists. Perhaps like vBulletin or other advance forum software. Maybe even built-in support in my email client?

For the life of me, I can't find a good way to use Mailing Lists. I don't like receiving 40+ messages every day, but I don't find digest mode good enough either. Google Groups is clunky, and it gives me no good motivation to return to it. The readability is also not all that great imo. The whole ajaxy thing it has going for it is also bad. I want to read static text on a functional and beautiful UI. It's not too much to ask for. :(
