This is an interesting opinion. In my entirely non-scientific observation of my first and only batch I've made I used a fine mesh stainless strainer when pouring the wort into the primary. Between the splashing of the cool wort, cold spring water and diffusion through the strainer I ended up with a very frothy wort. Fermentation took off after 24 hours using non rehydrated dry yeast (oops) and when I checked the final gravity yesterday it's down to 1.009 from 1.049. Point being, I think the wort aerated very well.
The one downside is I only have an 8inch strainer so the hops clogged it up before I could get all the wort in and some residue spilled over into the primary. Not a huge deal, but my effort to strain the wort out wasn't 100% effective. If you're going to use a strainer I suggest you get the biggest one that will fit over your bucket or funnel if you're using a carboy.
