I am now going to substitite "blu-tack" with "jQuery" and quote directly from wikipedia.
jQuery is a versatile, reusable putty-like pressure based adhesive
Check: When the project manager is breathing down your neck to "get that $%^%$ site out now", you can throw in some jQuery in a content editor web part and avoid writing anything server side.
But the clincher argument for me was this one…
jQuery can leave an oily stain on paper materials if attached for a long period of time.
Hehe! Although band-aids can hurt a lot when they come off, I think the oily stain metaphor is better 🙂
