Blog post (parody) - Metafilter thread - Mecha thread - dlcs marks.
I dlcs marked z0604 (April 11, tagged community)the mecha thread titled MetaChat - 50817 pointing to Metafilter thread 50817 which says One-link post about blog post without additional explanatory text (and is a link to a blog post on highclearing.com blog called Unqualified Offerings.)

post simply says: Blog.

to which, Comment.
then Deadpan rejoinder.
...
Accidental double-post.
Accidental double-post.
Apology for accidental double post, wasting even more space.
...
Assertion of position on the Israel/Palestine issue; claim that all who disagree are motivated by bigotry.
...
Pasting in an entire freaking article written by someone else, without attribution, as though it were one’s own work.

looks like some of the comments on the thread miss the beat. rather than naming the common instance, they enact it. (eg by making an irate comment rather than saying "irate comment".)

so what do dlcs notes call this exercise?

• Generic blog post. generic - that's right. unspecified. formal.
  

  - jbmurray
  

• Interesting collaboration on what constitutes a blog entry...complete with commenting sequences. How might we query about form?

  - AnaNg

• COMMENTARY

  - sunburntkamel

• note

  - duncanrobson

• Bookmark

  - shopiere

yep yep that's the spirit. I esp like "note".

• Snarky comment about how I've seen this before.

  - pmcaleer

right right.

mecha:
- Reunion tours are always so disappointing.
- No way, dude...this joke never gets old!

referring to 9622 | MetaFilter [Aug 2001]commenting in this style on a Metafilter parody on spoonfed.net (which is no longer there)
-Strong agreement with something only tangentially related to original post's point.
-impersonal double post notification [Nov 2000]

in the future everything will be annotated indeed
