I more than double my traffic with guestposting
Some days I am up to 600 users a day. Started writting for other sites about 7 months ago. This increase is mostly from guestposts as I also did some quora posts to help promote content. I only get a few visitors from quora. I keep telling people they need to do guest posts. I will let WA members post on my site for free, but it just has to be done well.
There are so many people on WA, why not network and post on each others sites to grow traffic?
