"I really don't think you have thought this through very well."
Actually hon, I've thought this through quite well ever since my then-bf got me into SL in 2008.
Phil, thank you for your reply. That's exactly what I think LL should do. There would be no privacy issues, but it would appear you can travel seamlessly between regions with no TP. They should implement your idea today!
Seamless flight would make the entire map seem open and inviting.
Another change I would like to see is that each island should be viewable from the nearest neighbor island. Nothing specific, just a smudge on the horizon that would let you feel like there is another place over there. I guess if some owners are so fixated on their privacy that they don't even want the neighbors to know their island is there, they could opt out. But I think the vast majority wouldn't have a problem with a neighbor seeing their island on the horizon and knowing there is someone else over there, building a home.
These might seem like tiny changes that aren't even worth it, but they would make the whole place more inviting and "real"-seeming. Simple things that wouldn't cost much but might pay for themselves in the long run by attracting or retaining residents. I for one would love to sit on a beach and see new islands being created on the horizon. Maybe even fly over and say hello if the builders permitted it.
