I never had the URL in the first place--and not 
having it used to drive me crazy (for about the 
first year that I collected), but now I could 
care less.  Frankly, I don't think my collection 
has suffered a loss on behalf of denial to 
Pocket access.  And after I got over it, I 
thought the whole thing was ridiculous anyway.

So if they disappeared--no big loss!
