1. Possible TM issue (celebrity name)
2. Probably not a good typo because o & u are not next to each other: http://www.remote.org/jochen/projects/jvc/keyboard.png
3. You won't get a lot of typo type-in with .ws anyway.
IMO it's worth nil.
Ditto. I really recommend someone new to the business stays away from typos. Stick with solid two-word .com's or save up for some LLL.whatevers and build your budget up a little to secure more valuable typos if that's what you are interested in. It can be fun searching for traffic typos, but in the end, I think I personally wasted valuable time I could have used researching strong keywords or developing more of my domains.
Sorry, but zilch. The value of typos is based completely on traffic and revenue, and you're certainly not going to get any type-in traffic on a .ws, and I don't think that "Angelina Julie" is even a common typo.
