These are valid concerns, so SWIM suggests perhaps a combination of a wiki and a periodical pdf release. This would perhaps be along the lines of open-source programming--nightly builds (an ever-changing wiki) that would eventually lead up to a official periodical release (the pdf). The wiki would exist purely for the sake of the collaboratory effort, while the forum remains for active research, speculations, and for technical support. A pdf would of course serve as the definitive reference; though to remain as such, it would have to evolve in accordance with the forum.
Of course, whoever writes the pdf will have the final say, but they will be hard-pressed to adhere to collaborative product rather than personal prerogative. Depending on how many SWIY's were deeply involved in this, the periodical release would have to be voted on or the competing editors would have to come to a unanimous agreement. A quarterly release would likely be sufficient for the pace of development.
It would be much easier to answer extraction questions with a good solid reference behind them. Plus, SWIM feels that many are being left behind or confused by the variety of teks and the variety of research on the forums. Some just can't dedicate enough time to a web forum to get the full picture, and if any progress is to be made in this field, a good solid platform must be provided.
