I see no point in doing it.
Eve if Google raised no comment now, that could change - and you'd (effectively) lose your site.
And Google might well do just that; your current plans may sound fine to them - but as the site evolves, they may come to believe it is misleading people; then you've lost the lot.
And whats the advantage anyway? Assuming you were not intending to mislead visitors :) , then you would not need to do it, and in SEO terms, the advantage (if any) is pretty small.
And if you are discussing adsense tips, I'm sure you'll use the word 'adsense' - one or twice.
Also, if you later wanted to widen your scope to get those Y! and M$N fans, you'd have maybe limited yourself.
Much better to develop a brand of your own, that is unique, distinct, protectable, and raises you above the other 20,000 adsense tips sites!
