I do, too, for the reasons you suggest and others. But you know as well as I do the "masses" couldn't care less. As with most things, adding more time to voting would change nothing for the 99 percent who either vote on the first or last day.
The basic problem remains that game extras yield to path of least resistance: Rule V -- set numbers, take whoever, even if they're drek ... minor leagues, f*ck 'em, not my concern .. HOF, too much work. Until the organization/simplification problem is addressed, nothing else matters.
You don't like the two-phase plan, Mike? Most owners would ignore the first phase, so essentially you'd have a veterans committee of owners narrowing the list, which is already happening in some worlds. Then what's left is essentially MVP/Cy Young-type voting, which is simple and straightforward.
