I'm with HBOC. I use my 80-200 for anything... some landscapes, street photography, outdoor sports, nature, portraits, animals, kids... almost anything. Of course, it's all telephoto, from medium to long(-ish.)
It will give a different 'look' than a "normal" zoom (17-55) more compressed, more subject isolation on closer subjects, more reach... but whether it's the right lens for you here...it kind of depends on what you really want to do with it in the first place, and whether it's the best focal length range for that expectation.
