I found this paragraph interesting in one of the links you sent.
Because the OTCBB listing requires you to be “fully reporting” and subject to SEC oversight and all that means including your independently audited statements and your “go to jail card” for willingly making material misrepresentations in your filings and statements, the investing public, institutions and broker-dealers have a much higher level of confidence in the accuracy and completeness of the information available on your company. Therefore you may stand a much better chance of finding an acceptable financing partner and potentially better liquidity for your stock with an OTCBB listing than you do with a Pink Sheets listing.
