I am using the List Randomizer to randomize lists of music chords so as to improve my skill at sight-reading music by practicing moving quickly from one chord to another on my musical instrument (upright bass) without either mind memory or ‘finger memory’ interfering by allowing me to increasingly do the exercise without actually having to read the chords. (I have found this to be a major fault with books supposedly designed to improve sight-reading.)

While I am sure that for this rather pedestrian purpose, a PRNG would serve as well as a TRNG, yours was the first List Randomizer I found after long web sessions of searching, and it's perfect for what I need. The nondeterministic feature of your TRNG—while perhaps overkill for my purpose—is definitely appealing.

My group at the US Environmental Protection Agency (EPA) is required by law to conduct audits of randomly selected facilities. I utilize Random.org for the selection process; the format of the query page is well suited to our needs. Until I found (stumbled upon via Google) your website, the recommended procedure for ‘random selection’ was to go down the list of items selecting every nth one; actually these items are industrial or municipal facilities which store/use more than a minimum quantity of a chemical from a list of 140 chemicals selected for their toxic/flammable and dispersable properties. I found this methodology a statistical embarrassment; Random.org made it acceptable, and defensible, such as when a facility responds ‘why me?’
