OK, after watching and tinkering with the new algorithm over the past 24 hours, we've settled on the final bits for v0.2. We'll upgrade the algorithm to v0.3 after the first of the year.
Many people have PM'ed me with outstanding feedback to help shape this algorithm. Almost universally, you requested that the BPLRank place significant emphasis on (1) tenure at BPL (as registered users, members, industry professionals, and staff) and (2) access to premium members' articles here, with the idea that tenure in a community allows one to develop long term trust, and that access to premium content here gives one access to a body of knowledge that can be used to communicate to others helpfully. v0.2 weights these factors accordingly.
Some notes about BPLRank ranges in general (note that these notes replace any numerical analyses presented in the thread above, but don't dramatically change any results).
BPLRank Range 0.00 to 0.33: This range typically represents folks who have been at BPL for < 1 year and/or who participate infrequently in the community here.
BPLRank Range 0.34 to 0.99: This group has an average tenure at BPL of 1.7 years, with a range of 0.3 to 3.4 years.
BPLRank Range 1.00 to 1.99: This group has an average tenure at BPL of 1.9 years, with a range of 0.4 to 3.4 years.
BPLRank Range 2.00 to 2.99: This group has an average tenure at BPL of 2.5 years, with a range of 1.3 to 3.4 years.
BPLRank Range 3.00 to 3.99: This group has an average tenure at BPL of 2.7 years, with a range of 1.4 to 3.4 years.
BPLRank Range 4.00 to 4.99: This group has an average tenure at BPL of 3.1 years (range 2.2 to 3.4). About two thirds of this group is BPL Staff.
BPLRank Range 5.00 to 5.99: This group has an average tenure at BPL of 3.4 years (range 3.3-3.4) and so far, is comprised entirely of BPL Staff.
BPLRank Range > 6.00: So far, only one fool falls into this range, which isn't good. Obviously the algorithm is broken, or does some kind of hyperbolic spasm towards one of its limits, so...anyway...we're working on that.
At this time, it is very important for everyone to realize that BPLRank is not necessarily representative of one's backpacking experience, but should be viewed as one measure of the extent to which people here have been involved with BPL over the long run.
v0.3 will be released in early 2007 and will result in minor disruptions to the scale as we evaluate contributions by BPL authors (staff and non-staff) and various measures of "impact" of those contributions at BPL.
By late summer of 2007 we'll install the algorithm's peer review subroutines which will be designed to evaluate the quality of postings, and the users' contributions, by the community.
Thanks for being patient as we implement BPLRank live and in stages. It's important for us to install each subroutine carefully and precisely, so we understand how it responds to community dynamics.
