Hello @theaustrianguy!

First of all, thanks for the effort you put into the welcoming service! 4 days ago you found my introduction post and helped me boost my start here at steemit. It made me instantly beliveve in Steemit as a wonderful community. Where else would you get so many welcoming messages, and even get paid for making an introduction? I think these posts will boost the number of newcomers to steemit. Just think about the effect when I tell my friends that I made $50 for my introduction post. I should show you a photo!

I am waiting to get my delegated steem back, when I do I will make an delegatin to @welcoming!

1. How many posts should I resteem per day? 10? 15? 20?

I have many times been thinking about unfollowing @welcoming as it overflows my homepage. I would say at maximum 7-10, but not more than three at once, as have been said earlier.

One idea that comes to my mind is to resteem the 7-10 best introductions, and then make a simple post with links to the rest of the posts. (like: These new users is also worth checking out: Abraham link. Benjamin link. Charlie link.) This will give you the opportunity to share more than 10 posts, and give us the opportunity to still follow @welcoming, and upvote new steemers as we do not have to let the frustration over all the new posts from @welcoming make us unfollow @welcoming. This sounds like the top five which also is posted, but it is not. It would be "The rest of the posts that didnt get resteemed :)

2. Should I also vote on introductions I don't resteem?

I think you also should vote for those you don't resteem, but only the posts you think are "real". (that might be self-evident...) You could do as the idea mention in question 1, and the also upvote those you put in the daily list. If you do not want to make such a list that is understandable, but I think upvotes would be nice either way.
