How well the documents are. If I got to go to stack overflow or a community forum to try and figure something out that should be found in docs then that is a warning sign.

What scope does the technology cover. I believe in the rule of "Do one thing and do it well". If it suppose to do A, but can also be used for B and C is a warning sign to stay away.

Is it something a engineer built or a hacker built. Not saying a hacker can't be a engineer and such, but long term vs short term goals for technology need to be well planned out and executed. I use a ton of technology built by hackers, but anything I put in production is built by engineer.
