 Cog·i·ta·tion [koj-i-tey'-shun]
– noun: Concerted thought or reflection; meditation; contemplation.
Kirt ['k?rt ] – proper noun: RF Cafe webmaster.
These articles were originally known as 'Factoids,' but the title was changed
because of the multiple (and sometimes unflattering) definition of the word.
Note: There is also a huge collection of my topical 'Smorgasbord' writings that might
interest you as well.
These original Kirt's Cogitations? may be reproduced (no more than 5,
please) provided proper credit is given to me, Kirt Blattenberger.
