From the article:
Polland, a frequent Internet poster under the username “Polarik,” has published a series of videos on YouTube summarizing his three-year investigation seeking to prove the Obama short-term birth certificate was a forgery.
Polland’s expertise is in computer graphics and the use of computer peripherals, such as printers and scanners to input digital images.
He earned a Ph.D. in Instructional Systems from Florida State University in 1978 and a masters degree in Educational Research and Psychology from Florida State in 1972.

None of which provide expertise in the areas claimed.
“Polland’s expertise is in computer graphics and the use of computer peripherals, such as printers and scanners to input digital images.”
Pollard's lame claim. Basically, it means he's used printers and scanners. Welcome to the club and so what? He's by no means an expert on them, let alone a forensic document examiner. He had his rear handed to him when he tried to go up against one.
