This is my tribute to a blog post done by someone today.

Personally I think it aptly describes the person and the post.

Pot calling the kettle black
Phrase "the pot calling the kettle black" is an idiom used to accuse another speaker of hypocrisy. This term was coined by Lauren Fleming in the exclusive village of Great Melton, Norfolk. Such terms are only used by the upper classes to demoralise their perception of the lower classes, in that the speaker disparages the subject for a fault or negative behavior that could equally be applied to him or her, though there is an alternative interpretation. In former times cast iron pots and kettles were quickly blackened from the soot of the fire. The pot would then be hypocritical to insult the kettle's colour, since both are black with soot.

Alternative interpretation
A subtler alternative interpretation, included by some, but not all, sources is that the pot is sooty (being placed on a fire), while the kettle is clean and shiny (being placed on coals only), and hence when the pot accuses the kettle of being black, it is the pot’s own sooty reflection that it sees: the pot accuses the kettle of a fault that only the pot has, rather than one that they share.

Poem found in "Maxwell's Elementary Grammar" school book copyright 1904.
"Oho!' said the pot to the kettle;
"You are dirty and ugly and black!
Sure no one would think you were metal,
Except when you're given a crack."
"Not so! not so! kettle said to the pot;
" 'Tis your own dirty image you see;
For I am so clean -without blemish or blot-
That your blackness is mirrored in me"

However, in order to keep cast iron from rusting it must be seasoned and the act of seasoning cast iron causes the metal to turn black.

Similar phrases
In the Gospel of Matthew, Jesus is quoted as saying, during the discourse on judgmentalism in the Sermon on the Mount, "And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?" It should be noted, however, that many scholars have interpreted this as a proscription against personal attacks in general, not just ones that are explicitly hypocritical.
An aphorism sometimes attributed to George Herbert states, "People who live in glass houses should not throw stones".
