Then why don't they show up when one does keyword Ukraine as even Lukasz noticed? (attributing only 2 of Lizol's articles to her).
Because Lukasz restricted the sample to the 20 most recent posts (at the time).
Of the 10 posts you listed in #14:
1 doesn't show up if you execute a keyword search for Ukraine, as I pointed out to you
1 is actually amongst those Lukasz tallied
The rest will show up if you simply look further back in time using a search using the keyword "Ukraine", between 11/30/05 and 1/3/06.
Just for sh*ts and giggles, a sort of the last 500 posts under keyword "Ukraine" produces the following tally:
500 posts.
79 unique posters.
jb6 200 posts
lizol 62 posts
twinself 24 posts
mazepa 22 posts
lukasz 21 posts
x5452 19 posts
tailgunner joe 19 posts
leocarpathian 13 posts
spanalot 8 posts
apole 6 posts
sergey1973, garyspfc, & alouette, 5 posts ea.
and 65 statistically insignificant folks with 3 or fewer posts.
So neither "side" of the Ukraine issue has an outright majority, a fairly good picture emerges as to which side has been more active on the issue.
Thanks to UNIX utility programs: grep, sort, & uniq
