Just this morning I found out many of the links to Picasa photo albums were not working. This was due to me screwing around with the privacy settings of some albums, and messing them up for many of the other albums.
I just spent time fixing the permissions, and all the albums referenced in these blog posts should now link correctly, including those of the 2009-2010 Hawaii trip. That particular post actually links to a number of Google Documents which in turn link to Picasa Albums.
I will probably redo that one eventually, but for now it works.
If anyone hits on a “dead” Picasa link, or any other dead link, please leave a comment in the appropriate post.
