Every couple days a new coin comes out that gets abandoned by the dev. I am having trouble understanding the thought process of this. My guess is it is either one of these options.

• The dev is extremely lazy and/or has so many other coins that they cannot keep up with them. The plan is to release a coin, hope they get support and come back days/weeks later and dump a bunch.
• It is actually a well thought out plan to get people to waste their hash on tons of junk coins while the big miners mine all the "good" coins.

Could there be any reason I am not seeing?
