If the invisibility cloak is so good at shielding people from death AND the Potter/Peverell family is focused on defeating death, why didn’t James put baby Harry and Lily under the cloak as soon as they knew Harry was a target?
Harry is going about his daily life under cloak w/ broomstick now; surely his parents—who spent more time with Mad Eye than Harry has—would appreciate the need for constant vigilance when Voldemort wants to kill your baby.
Roland, piggybacking on couchsurfing.org’s preexisting infrastructure could be very easy. However, I can think of a couple of reasons why it would not be as effective as adding a google map to LW.
1) There is a big cognitive cost to making a new user on couchsurfing.org and checking it for messages every so often. I’m assuming people in the LW community have a LW username and periodically check their private messages. It would be psychologically easier for people to not have to sign into multiple sites and manage multiple inboxes.
2) For the whole “look at the traveler’s (or host’s) posts to see how long they’ve been a member and read their posts (a fantastic measure of how interesting or obnoxious the potential traveler may be)”, people would have to make couchsurfing profiles that have their LW username, references, how they want to be compensated/how they’re willing to compensate. Then, whoever was reading their profile would have to go back to LW to look up references/the users’ posts. This seems pretty annoying. It would be much easier to just have everything on one site.
3) Not very important, but I’m not sure how many people want to put personal details on couchsurfing.org. I’m also not sure about how couchsurfing.org works, but I would prefer for only people in the LW community to be able to contact me re: staying over.
