Although the date may not be relevant for the post, at least I like seeing it at the top. Then I can get a sense of when it was written and decide if some of the concepts in the post is outdated, even if the post as a whole isn't.
But as you said it's always good to try new things, especially if you measure the difference.
I'd love to hear what your results are.

Not the best post to read right before going to bed, hehe. I feel like I should run and do something, like starting all those things I've been planning to for a while, instead of messing around. Well, hopefully I'll feel the same tomorrow.
