My take on this whole question is a lot different. Boost libraries cover a wide range. Quality of design varies from good to excellent Quality of implementation varies from good to excellent Depth of documentation varies from minimal to complete. Quality of documentation varies from OK to excellent Runtime performance varies from abismal to good and maybe excellent in some cases Support from library author varies from non-existent to immediate Some libraries will work on all compilers, others only on the most conforming Stability varies from rock solid to - work in progress etc, etc. In the quest for excellence - which libraries are you going to set aside? All libraries are useful to someone - and likely more than a few people. And I might use a library that is less than what I want in some aspect because it's still better than rolling my own. So the idea of imposing more and more infrastructure to get better quality wouldn't work. And if implemented would result in a smaller number of useful libraries being available to those of us that need them. What I really need is a better way to assess the library along the above dimensions. Making this type of information publically available would help me decide which libraries to consider and would let authors know what they need to address to make their libraries more popular. So here's an idea. A special web page accessable to anyone who has downloaded boost. On this page, one could indicate which libraries he uses/has used, etc. and rate them along the dimensions above A - excellent B - good C - OK D - below par F - sorry - but this sucks and there would be space for a short comment and for the author to respond. Then if I'm considering using library X, I could check out the "ratings summary" for this library and decide whether or not to risk investing my time in it. While, we're at it, lets include boost tools in the above system as well. I've now convinced myself that this is such a great idea that when I have nothing else to do, I'll do this myself just to drive traffic to my web site. Robert Ramey
