Though would be a waste of time posting a poll. Mint HQ no doubt has enough on their plates, are already juggling this, that the other 10 things. Really doubt they'd drop what they're doing and the goals they have to accommodate 20 people voting on a LM forum poll.
From what I've seen and understand, buntu releases often break people's stuff. Even doing a fresh install from one 6 month release to the next. With all the changes and alterations incorporated sounds like a recipe for borkage. Now LTS releases or whatever ... still really think the same is a likely outcome. Canonical is certainly not world renown for listening to the needs of that distro's community. Or for quality control in general, hacking Debian and spitting out 1/2 baked releases at breakneck speeds. Many of which the end users of the distro obviously don't like, as if canonical seems to care. Noticed the number of people jumping off the buntu train popping up in the Mint forum ? So buntu does it ... isn't saying much imo. Buntu does a lot of stuff that am sure the Mint people spend more than a tad of time cursing and kicking stuff over. Stuff such as dang it ! We have to deal with this, that, these, those and thous to try to smooth out canonical's software quirks n bugs !
Also seems LM has rolling releases out. Which one of the selling pts, is supposed to be no reinstall's necessary. And the virtue of being Debian based vs buntu. Might want to give them a gander. Other random babblings to include. If the volunteer devs associated with LM and LM HQ can spend who knows how many gazillions of hours cooking up software, trying to please everyone and their aunt mertle. Then doesn't seem all that unreasonable to expect the people who use certain releases of their software to be willing to spend some time reinstalling a fresh release and importing whatever data they like into or keeping such on a seperate partition for easier migration or or or whichever of a bunch of other methods to ease the migration pains. Only 2 cents on the topic. Errr ... pointless 2 cents nm ... sighs.
Remember seeing a post, linked to somewhere in these forums. Where Clem said he's spending 2.5 hrs a day working on LM. Do the math there, considering it's opensource software, with a few ways of making revenue but no pricetag. That's quite a bit of time sunk in, by one person involved. Think about it ...
