My interest in stickers or other labels depends on a few factors. If a "disposable" item such as a wheelset, then all stickers are promptly removed regardless of cache or the maker. I also have a strong dislike for big whirly thingies (if forced to drive past a wind farm, I get very punchy for some unknown reason, no need to bring that feeling home, but I digress)...
On a frame, I'd like to see tubeset, serial number, and origin stickers, but please as small as possible. For the latter two items, engraving on the BB shell or somewhere inconspicuous would be preferred. Stems, bars, etc - if the manufacturer can't take the care to engrave it to look awesome (like nitto bars for example), then I peel away whatever sticker they supplied as their lazy alternative.
