Thinking about removing local scout, I don't particularly use it.
I'm an SEC football fan, so I use Team Tiles to pin a "Gig'Em Aggies!" flip tile to my start.
I also use "Woot Tiles" to pin the latest Woot.com products to my start.
I also REALLY like that I can use the kindle app and pin the specific book that I'm reading to my start page, and I like that I can pin my created Nokia Music mixes directly to my start.
I hope that as more developers/apps come online, that they will continue to allow to create custom tiles that suit your needs.
Disclaimer: I programmed Team Tiles and Woot Tiles... so I'm a little biased there... ;)
