Lunchtime Poll: Are old CityVille buildings worth keeping?

Landmarks
CityVille is a game that constantly evolves. The items of yesterday just aren't as impressive as those released today, but what happens to those items that get left behind? CityVille forum contributor Tara424 has created a four-page thread discussing what players do with their old and busted buildings. Players appear split down the middle between keeping the buildings for old time's sake and moving on to bigger and better things. So, we're bringing this hot topic discussion to you:

Old CityVille Buildings: To keep or not to keep?
I like the diversity they bring to my city, so keep them!When you have buildings taking up less space with higher payout? Leave 'em!I don't really pay attention to this stuff. I just play as I go.Who cares how good the building is? It's all about the decor!

CityVille: Collect from Houses, get random population boosts

CityVille Population
Sick of adding variety or flavor to your cities with new houses to increase population? (Who needs 'em!) Zynga has introduced an interesting update to CityVille that, when players collect from Homes, will randomly drop population increases. Remember that strange little phrase many of you found next to building information in the Market? You're looking at it.

Whenever you collect from a Residence, there is now a small chance that, in addition to coins and XP, a small moving van icon will appear. Click on it and you'll receive a small overall Population boost in proportion to the Residence you collected from. However, each House you own has a cap for how much it increase your population by, again in proportion to the home's original. So, this is a temporary fix to a growing problem: space.

Have you seen this new feature in your city? For how long do you think this will alleviate the growing population versus space problem in CityVille?
