Better to continue discussions than reinvent the wheel and create new threads requiring repeat posts of consolidated preserved information and clutter the system up with parrallel threads.
Most times, just because a thread is old doesn't make the content obsolete.
Most forums have longer threads covering chain lube favorites that degenerate into heated flame wars-so this is a topic that brings out the trolls.
1) I'll stand by my post above. I've watched it happen too many times.
2) I've suggested, on numerous occasions, that BF create sticky posts for
degreasers, grease, and chain cleaning and lubrication, generally.
In my experience, the amount of valuable information added to these threads -- new or old -- greatly diminishes with time as historically knowledgeable posters simply tire of seeing the subject raised yet again.
Because they ARE such staples to the subject of bike mechanics, there DOES seem to be value in letting people -- particularly those new to the site -- find the accumulated wisdom of the forum's members in a single place, WITHOUT having to perform a forum search.
I also think their presence as sticky threads will INCREASE the amount of participation, rather than generate the expected "oh, God. Not another chain lube thread....." that's always seen on bike tech sites where new lube/grease/chain cleaning threads come up more often than flats in goathead country.
If it's always there, I'd guess that participation will increase and fatigue will decrease.
