Hey Andy,

Before this changeset, this island was traced badly. There were jagged edges which do not reflect reality. The changes I made were minor but do improve the outline as seen in achavi here:

Do you have anything that shows Bing is offset here? osm.wiki/Prototype_Global_Shoreline 
The edits I am making are generally good, and can always be improved upon once Bing offset is known or rectified.
Thanks for your comment,

Jason

Sorry about that, I accidentally uploaded a changeset form a previous edit. Thanks for letting me know, and I'll be more careful next time with dragging nodes. Thanks!

I focused on Gosti Island because I found it through a Maproulette challenge designed to find jagged islands that can use better alignment. I am part of a small group of OSM users working on improving these islands.
