Rollerblading

So recently I've been thinking about taking up rollerblading (in-line skating for you pros) as a hobby after I've partially fallen out of love with cycling. I've seen a few people in the park having a go and I think it could be a good laugh.

Are there any BBS'ers out there that are in to it and and can give me some advice? I've got no idea about skates or pads or anything so a tip or two would be great!
