I agree with
@That Guy .
There has ben a lot of discussion about Stokkebye bulk blends recently. In the short time I've been a member here, I've noticed that frequent discussion of a blend often results in the blend either being out of stock and/or jumping the ranks on SPC's best seller list.
Not only does discussion result in members sampling or restocking blends, nonmembers also access the forum. Hence, sponsoring the site seems to be a decent marketing strategy. Just look at the seemingly increased traffic at site sponsor TinBids.
You don't know who is viewing the forum at any given time. For example, 44 members were signed in to PM when I began this post. 136 guests were also viewing the forum.
It's also why people should always be careful about what is posted on any website.
