Eh... that advice really isn't great with the newest version of Thaumcraft. The newer updates of Thaumcraft had hard to obtain crystal clusters you can craft out of Infused Shards. These crystal clusters will actually slowly replenish the aura around it up to 10% higher than the effected node's max aura. This is a good thing as it can regenerate Infused Ore that had been turned dull. Now, I could be wrong, but what I've seen and heard so far suggests it takes an excess of 100 aura over a node's max to get it to generate Infused Ore from plain Stone. If that is indeed the case, then you'll want to build up your work node to at least 1000 maximum aura, because it is at that point you can use crystals to actually create more infused ore and start creating aura instead of just replenishing it.
Fair warning though, nodes with aura in excess of their max generate flux. You'll either want this to be a Pure node or you'll want to have a distant node set up to regenerate the local aura while you work a safe distance away at a node with much less flux.
