**Recommendation:**

Choose the description that best reflects the types of content you’ll be tagging with “閱讀器”. If you are writing articles that focus on comparing and contrasting various e-readers or offering tips to get the most from web-based RSS readers or other types of tools, you will want to go with option 3 or 5. If the tags are primarily meant for finding information related to the overall concept of “reading,” options 1 and 4 may work well.
