I would say the post quality is good but not the best. My english level is on the level of native speaker .
Most comes from Marketplace -  currency exchange (mostly warning people and trying to explain how to trade safe - refering escrows, did very few trades by myself) /Gambling /Services / Digital goods. Nothing in altcoins or offtopic.
Very few bumps.

There are some threads in Economics and Securities from when I used to promote the articles I wrote for various bitcoin networks but those are a little older.
