Great job Ergo!
I'm diversifying myself to 20k-20k-20k between LLL.coms (both of which are being developed), LLLL.coms, and LL/LLL.ca. I have about 5k worth of LLLL.nets.
As for the more speculative investments, I have 10k invested in .mobi aftermarket purchases, 1000 VCVC.infos and 90 N-NN.coms.
It's a nice mix of various short domain segments, each with different risk levels. By doing this, I limit my risk should any 1 of these particular segments collapse, but do unfortunately limit the return a bit by not going "all in" in one or 2 segments.
