Apologies if this was another mistake. It's just a little suspect when things get as glowing a review from people who don't otherwise comment.
I get your point, and it is true that I'm not active on HN. However, that has nothing to do with the credibility of what I wrote. That is exactly why I made sure to share my background in advance.
If you take a look at my submissions you can see that I'm actually working with a lot of Toptal developers that are producing some great technical tutorials, tips, etc. Which is another great thing Toptal has. We share for free a lot of valuable technical knowledge and we spend a lot of effort making it.
