Blog etiquette

Because my blog is mostly (if not completely) anonymous, I don't feel the need to lie. There is no reason for me to do so.

Are there people out there that lie in their blogs to help in making themselves believe they lead a life that they really don't? Or to take them away from reality?

One thing I do do though: sometimes if I haven't written a post in a couple of days and I then write multiple posts in one day I change the dates to disperse them over the past few days, to distribute it more evenly.

Is that okay?
