No problem! :)
I usually recommend to people to find 2 (maybe 3) 'higher traffic tags' that actually apply to the post, with the remainder being anything you think applies and might be something people would check the feed for.

You can see a big list of the bigger and more frequently used tags (with the post and $ earned count) here:
https://steemit.com/tags

However, as you get more a following, people start looking for you specifically more often, making the need for the tags reduce a bit (though still helpful.)

..and if you didn't make very much on your intro post (say less than 5 or 10 bucks)...you can always do another one...especially if it's been a little bit and you can include some of your first impressions of steemit, what you've learned and mention that the intro tag wasn't right the first time.

I really don't see people have a problem doing things like this..which is easily seen to be different than those just trying to 'exploit' the tag.
