Thanks for your observations. I'll make a panorama author link more visible.
Permalinks are a problem, I agree. I would, for example, like to have links like panoye.com/country/city/panorama-name.html but the problem is with google maps. When you signup for your gmap key - you have ONE key for ONE directory on the web server (for example country/city/). It means that I should have (and use) houndreds of gmap API keys :(
Thank you again for your comment!
