Proper tagging can be tough when you are first getting started. But this community is far enough along that I would start questioning the usefulness of these tags at all.
Having an overused, catch-all research tag on a Genealogy site is like having a programming tag on Stack Overflow. What does it actually tell you about the question? It's largely ubiquitous.
Tags are supposed to tell you what the question is about. Tags like brick-wall and road-block do not tell you what the question is about. Saying "I'm stuck" only tells you why a question is being asked. In Stack Exchange terms, these are called "meta tags" and are explicitly discouraged.
The Death of Meta Tags
Unless you expect a lot of questions about "road blocks" and "brick walls," you should try to start editing these out. Tags should organize and categorize the topics being asked. These meta tags will only mislead users into a false sense that they have adequately described their question without actually helping with the topic organization. You'll end up with a bunch of tags like [im-stuck], [hard-question], [poll], and [advice-needed] — and these questions become exceedingly difficult to discover.
