Understand you don't, little padawan
The target of this is NOT banks, big oil,... its the REAL big guys, Google, Amazon, Yahoo, Facebook etc.
You'll notice the COMPLETE -and deliberate- lack of user-friendlyness, basically the configuration has to be done with a hammer and a tiny chisel to carve the 0s ans 1s manually on the disks. It is a lego brick to be incorporated in big datacenters in lieu of the comparatively bloated MySQL, not a complete, luser-ready system.
Also I'm sick of people complaining about open source names just because it's open source. Apple OS is a stupid name, and Windows? Seriously? Skype? come on. .NET? How could you get more horrid than .NET? Oh right, that would be iPad. Or Java. Seriously, Java? Puh-leeze. etc...
Names are just tags, and that's especially true for backend software. For all you know your "conservative" bank software might include a module named WhoeverUsesThatCrapIsaMoron, but only the seller's devs would know. Same as for Drizzle. You're not likely to notice if Facebook starts using that, are you?
Also, I did not know that banks had a need for the Gnu Image Manipulation Program, although if they had, they would be complete morons not to use it based on the name alone, and I, personnally, think you're pulling that crap out of your arse; no high-level manager will dismiss a saving of million dollars based on a seemingly silly soft name. There would have to be REAL reason. Only deadwood middle management types and the coloured-crayons department give a rat's ass about software names. The rest of us use the right tool for the job.
Which reminds me that I need to rename my latest project Hammer. Because Hammer is always the right tool for the job, Or something. The next one will be Ductape (possibly with a logo featuring a large simian creature just to add some confusion). Cubicle drones might not get it and find the names silly, but if it's aimed at techies it will make a killing.
