After reading the thread, I recently modified my technique. I have been getting a consistently nice sweet creamy steamed milk for my cappuccinos, but my latte art has remained pretty non-existent, which I attributed to having a new machine for less than a year and making less than a hundred milk drinks a day.
However, after thinking about it for a while, as the new machine has a four-hole steam wand tip, I changed the direction of my steam wand. I had previously pointed it down fairly straight, perhaps slightly outward. I changed that to having the wand closer to hugging the side of the pitcher, pointing perhaps slightly inward.
This results in a terrific whirlpool effect, rapid volume buildup of foam, and homogeneous, sweet microfoam which develops quickly while the milk is still tepid-to-warm, and a nice rosette today. The whirlpool effect now looks very much like you are beating eggs or batter in a bowl.
Anyone who has been getting nice sweet microfoam, but finds it a bit hot, quick to separate, and bad for making latte art, ought to consider the angle of their wand in the pitcher!
Of course, I still use cold milk, keep the wand just below the surface to get the "sucking/ripping" noise, and do everything else you are supposed to do. Just remember, the wand/whirlpool is important as well.
