Yes, it makes a lot of sense, and I agree.

Right.

Meaning...?

I wouldn't be too sure it's so complex... then again, I'm a math geek so I
wouldn't know ;-)

The last two are, IMO, HUGE advantadges for the [0,100] system. Percentages
are pretty damn intuitive in most cases, and it's easy to relate to them.

Yep, one other point. I'm not sure if it's an advantadge or a disadvantadge...
But:
In the [1,100] system, a post without votes would be rated as... [50]
If I'm the first voter, vote for 100... the system (supposedly) adds vote,
making the post... [75]?
Just making note, I dunno if this is good or bad, just sorta weird.

Yah! I agree!
