While Coinwarz(and similiar sites) is often a good metric for profitability, its fundamental flaw is that it only looks at two things- difficulty and price.  What it doesn't account for is the possibility of network issues with the various coins.  99% of the time, if a coin is leaps and bounds above the other coins in terms of profitability, it's because the coin forked and Coinwarz is on the lower difficulty fork.  So miners say, "Holy jeebus, I can make $500 a day with my 7790!", and then find out later that it was bunk.  Without verifying the information in the coin's announcement thread, you're just mining blindly.

As Regean said, "Trust, but verify."

As far as my news post not being entirely accurate- I believe that the people mining should at least have a grasp of the basic ideas and terms used in crypto.  That being said, if I wasn't aware of what an orphan is, I'd make sure I found out quick if what I was mining was having an issue with them.  That's just putting two and two together and getting four, mate.  I'm a pool OP, not a math teacher.  I can't hold every miner's hand and explain to them the ins and outs of mining.  It's their responsibility to be knowledgeable in their endeavors, whether that's in crypto or in life in general  .

For anyone who isn't sure what oprhans, or forks, or any other word thrown around in crypto means, there is a glossary at the following address for your reference.
