90% of the time your nodes are 20-40 lines long? Are you sure? I checked your last 10 nodes (as of this writing), and here are the line counts:

395203:  7
395121:  2
395117:  3
395114:  4
395101:  1
395093:  3
395092: 11
395090:  2
395089: 14
395010:  1

This is using a window width where your signature itself uses 6 lines (excluding the disclaimer you sometimes use below the sig). I didn't count blank lines, but I did count lines of code that had just one character on a line. This, admittingly small, sample uses an average line count of 4.8. Which is less than your sig. In fact, only 3 out of 10 postings have more lines than your sig.
