Are they really necessary? For my niche, the blog entries I will be making, will always apply and so I don't see why dates are important. I don't want readers to see old posts and not look at them because they only want to read what is new. I also don't like how they can see the space between the times I made the entries. I know, I can change all the dates but I don't want to keep up with that. Thanks for your advice!
