Yes - it's normal.

It doesn't really matter and it's a good thing because you know if your rankings are wandering up and down in the rankings then you need to do more promotion until they stick.

Some people seem to think getting your website ranked is a one-time thing where you do the promotion and then forget about it.

That's obviously not the case and with Google's focus on new and changing content it's only likely to get more important to keep your promotions constantly running in order to keep your relevance and content fresh.

I just check the rankings once a week. The rankings will go up and down daily and it's not much a big deal.

In my experience, newer sites will dance around more, older sites will usually stay put.

Depends on the keyword though, remember, your competition is building keywords too!

It's not a new thing, Google dance has been in existence since the beginning of times..

Thanks for the comments, from past couple of weeks there is drastic change in the rankings for my website on daily basis, please cross check your keywords on daily basis to know the change.

Because others are doing their best to get to the top as well? SERPs are not static. However after Google Penguin update I am also facing the same problem. I feel it is because of Google's change in rules as well as backlinks which is getting cached randomly making the linked websites move back and forth.
