Hello,
I just wonder about a list that includes both well-established experts that focus on PostgreSQL (ex. EDB, Crunchy Data, Data Egret, PostgreSQL Experts, etc.) when companies with 1 employee and without a working website are also on that listing (ex. PostgreSQL International). Seems like there should be some basic standards for being listed, for example: you are a registered business, you have more than one employee (ie. you haven't just created a name for your one-person consultancy, there could be a separate listing for independent consultants), you have a working website and up-to-date contact information, you follow PostgreSQL community standards/OSS policies, etc.
There also seem to be a number of companies that would be difficult to categorize as "PostgreSQL specialists" considering the breadth of their work and expertise, ex. Heroku, Savoir-Faire Linux, Web Global Net, Moki Systems, etc. yet they are on that list. This could be the start of a slippery slope.
Personally, I would struggle to pick out a reputable company with real expertise/focus on PostgreSQL from that listing at present, if I did not have any other familiarity with the companies.
Sincerely,
Katie
