Well the first Q drops contained some of the most specific claims for what would be happening, with dates, and none of those things did happen.
After that Q went to the Socratic Method, and then a bit later started sharing links from various press sources more, too.
So, the first few are among the least convincing.

Hillary Clinton will be arrested between 7:45 AM - 8:30 AM EST on Monday - the morning on Oct 30, 2017.
HRC extradition already in motion effective yesterday with several countries in case of cross border run. Passport approved to be flagged effective 10/30 @ 12:01am. Expect massive riots organized in defiance and others fleeing the US to occur. US M’s will conduct the operation while NG activated. Proof check: Locate a NG member and ask if activated for duty 10/30 across most major cities.
If you believe what Microchip and Dreamweaver have said (and I realize most here do not) they both dropped out of writing Q posts in the 4chan era.
That means that there is at least a chance that the 4 chan start of the Q posts were 4chan guys having a fun time, and the later 8chan posts were taken over by someone else, perhaps even someone more connected to Trump.
