It looks like all your questions have been answered, the only thing I have to say is welcome! Do not let the low activity of the site make you think it is dead, people here are the type of people that read articles and post long, thoughtful comments, that takes time so you will probably see less comments but with more information and better discussions.
Wednesdays in particular is the exception with #pubski. You'll see lots of action in there. Pubski is a sort of open forum where the post is treated like a pub where people can talk about whatever they want. It coincides with veen and rd95's stressors of usernames matter since you'll see many people discussing events in their lives that may be a continuation from a post, last pubski, or serve as a springboard for a future post. To this end, I guess this could go under veen/rd95's comments, but I recommend checking out #3questions , #meethubski and #adayinthelife to get to know some peeps or even contribute your own piece!Do not let the low activity of the site make you think it is dead,...
