Rick Mansfield of This Lamp has reprinted a paper on the HCSB by translation committee chair Dr. Edwin Blum, titled A Comparison of the HCSB with Other Major Translations [Edwin Blum]. There is a certain favorable bias toward the HCSB here, and a bit of salesmanship, but overall there are also many good points about the approach taken by the HCSB.
MyBibleVersion.com has a summary page on the HCSB.
