For Powwow you have other companies, all domains are taken, and you will have to fight wikipedia to rank for this term in any top spot. Same with otto, the car company. Otto is popular first name, name of one of the largest European pre-amazon retailers, etc.

I purchased powwowjs.com (js because it's a javascript embedded app) for $40 after spending 15 minutes thinking about a name I liked. I'd rather spend my time and money building a product that is not yet validated. If the name needs to change, that's totally fine and a lot less time consuming than my current task at hand.
Not criticizing the content of your project, but I think you make it harder for yourself than you needed to. Several avenues are blocked right from the start depending on name choice, and rebranding is really expensive.
