Lifehacks SE will now be starting to do fortnightly topic challenges as many other SE sites have done over the years. We need to do a few things before the topic challenges can be started and one of them is to create a post asking for themes for the topic challenges. This will be that post.
The themes for these topic challenges will be tags on this site (ie: home, car, etc.). These can be popular tags or tags that you think should get more attention. So, please suggest any tags you think will be good as an answer to this question. Also, vote for your favorite themes. The top theme at the end of every two weeks will be used.
Note: Topics that are chosen will be deleted to avoid clutter in the answer section.
