I frequently post in #minnowsupport and #whalepower since discovering the tags, also #minnowsupportproject is a good tag to follow for supporting each-others posts.

One BIG tip I have for all minnows is to do what I do. A few times a day go through the top 30 or so of "new" and "whalepower" and look for topics that interest you. Upvote 5 of them! You will still have 5 of your votes for other things.

Another tip is comment, thoughtfully, on any post you find interesting. Many "Dolphins" and "Whales" do look at minnows posts for thoughtful comments, they follow and upvote those who make them.
