@Colorado_Moms: If it's your first holiday away from your family, this could come in handy. Technically, it's supposed to be a resource for new moms, and I am sure it is great for that. But it's kind of like having a handy mom surrogate on Twitter! They've already been tweeting links on how to make your own holiday decorations and deal with holiday weight gain, which are pretty Mom-type things to tweet about. So follow them, unless your own mom is already on Twitter supplying advice on decorating and nagging you about not gorging on turkey.
@Colorado: This is the Twitter feed of Colorado tourism's official site. But you already live here -- so why should you follow it? Because if you've got family coming in from out of town, they're going to want to see some touristy Colorado things, and if you're like me, you have no real idea what that might be. Seriously, when your out-of-town relatives ask, "So, what do you all do for fun in Colorado?," do you think they'll like hearing, "Drink in dive bars and smoke medical weed," even if that's the truth? This feed should hook you up with some more acceptable answers to that question, not to mention suggestions to keep the in-laws out of your hair.
@IKnowDenver: This is an encore shout-out for this feed, but it's a good one, since it shoudl provide you with a deeper look at stuff to do in Denver than the tourism folks above. Seriously, next to @DenverWestword (even if we do say so ourselves), these guys are one of the best places in town to find cool stuff going on. And they've dropped some good holiday-themed stuff in the past days, like a Santa-themed pub crawl! And there is surely more to come.
