Stop Cross-Posting Please! (was Re: genid example from RDF1.1 is bad)

Please stop cross-posting!

Henry, the W3C Mailing list policy says

    Each mailing list has a specific purpose; please try to avoid widely
    cross-posting to multiple lists if possible.

Your (and David Booth's) initial cross-posting of your comments about 
ld-patch were unnecessarily cross-posted, but I could at least see how 
it was in-scope for the lists you each chose.   But this email has no 
business on public-ldp-comments or public-ldp. It's also problematic to 
cross post to an official comments list like public-rdf-comments, since 
it lures people from other lists into making what might be official 
comments, forcing the relevant Working Group to do more work to handle them.

Finally, I need to comment on your tone.  Many of us get passionate 
about technical issues we care about, and it's possible I've used words 
like "repulsive" as you did about a design I didn't like, but if I did, 
I soon regretted it.   If a design seems that bad, particularly one in a 
W3C recommendation, it's probably because one is misunderstanding it.  
And if the designers did make a colossal mistake, calling it "repulsive" 
isn't going to get it fixed any faster.

Thanks everyone for helping making the Web and W3C relatively nice 
places to be.
