I have seen a few questions where people want to do something like convert a file, or they ask a question about a specific programming tool. Then they don't tag the post with the programming language they are using, and or don't tag with the file formats they want to convert between.
How can we as a community moving forward encourage proper tagging? Should we make a one tag minimum, to remind people to use tags?
Possibly allow more than 5 tags. In bioinformatics it would be easy to use more than 5 tags every post. Possibly we could have 0-2 coding-language tags then have the other standard 5 tags.
