iframe or not iframe

recently I have noticed loads of skate (or skateish) sites using iframes to display in particular news pages (usually in tiny print). I’m undecided on them. I’ll agree they look good and keep things neat and compact, and i’m considering sticking one or two on this site, maybe for recently updated items and my skate blog. On the other hand they can be a bit fiddly – i’m not convinced they encourage people to read the contents.

I’ve also noticed a lot of people using the word "plethora", sometimes quite unexpectedly and out of context
