Meeting and discussion with major experts in the field. Good opportunity to meet relevant people in the field and exchange ideas. Sometimes it is difficult to read OHP because character is too small. Not enough discussion time. Not enough time for discussion during poster sessions.
Scheduling needs improvement.
More parallel sessions are needed. Early starts, but that was necessary. The extremely poor timing of lectures. The nonchalance shown by very many poster presentations. More specific attention paid to analytical measurement problems in their areas of expertise rather than overviews of SRMs that are available.
