I think it is about increasing number of posts, so we need really interesting original content to get more votes. The second - it is good to post with not so popular tags like technology, but your post should be really relevant to the tag. That is I am going to do in the nearest future )
Thank you for your input! Yes, the number of posts keeps increasing, while our filter options stay quite limited. I do hope some day they will add some extra ways of filtering. I made some suggestions in a post in the past, but it went by unnoticed, just like many other posts :-)
