I usually avoid linking to Yahoo! News because the links tend to break quickly. This list of Space and Astronomy websites might be worth saving for a while, however. While I was on this subject, I enjoyed clicking around the Yahoo! Science Directory, and realized I had not even bookmarked it.
After visiting and attempting to visit various abandoned and unlinked, or relocated websites, I came to the rather metaphysical and positive MemeCentral.com. Maybe the Meme meme cannot survive very long in scientific environments.
