Related nodes by taxonomy term in a view block
I've done a little tweaking myself, and I seem to have gotten a working solution here.


Create a new block for the nodes you'd like to display
Add a new Contextual Filter: Content: Has Taxonomyterm-ID
Select: "when the filter is not available, provide a default value: Taxonomyterm-ID from URL."
Put a check next to "Load Standard Filter from node-page, useful for related taxonomyblocks"
And you will probably want to limit the vocabulary as well


In order to exclude the current Node you have to add a second Contextual Filter for Node-ID, provide default value as the content ID from URL and at the bottom of the modal pop open 'More' and check 'Exclude'
