eBird should totally, totally develop a tool that allows users to detect whether their personal locations are very near hotspots (or should be merged with the hotspot). Maybe they are working on that, but in the meantime here's a little app to help you clean up your locations and get your name on more Hotspot Explorer pages :)
Hotspot Alignment Tool
To use this program, download your eBird data (the link is in the My eBird page on the right toolbar), then upload that file directly to the page.
This is just a primitive idea of what a tool like this really ought to do, but I just wanted to share this little functionality with the eBirders out there in case it can be useful.
