This is a really useful topic for a post. Thank you!

I'd add the AskSteem.com site by @thekyle to such a list also, as a suggestion. It's essentially a search engine targeting only Steem blockchain content, whose more sophisticated search options people might find more useful for finding articles of interest than Steemit.com's basic search function (e.g. boolean searches and such).

One of the things I found frustrating when I first started lurking here was my initial difficulty in finding what I wanted to read amongst the sheer volume of content available. AskSteem did end up helping me with that significantly.
