Special note: Here''s a question I get a lot:
Q: Why did you miss (or miss us) last time?
A: This is a misconception that stems from the variability of the forums I
    cover each (semi-monthly) period. The set is not static; rather,
it''s
    based primarily on traffic volume. To illustrate, this period
    website-discuss didn''t "make the cut", but in previous
periods it did.
