Why not take a bit more time to learn your way around ATP. There are many good discussions about plants which are considered to be weeds by some people and are valuable plants to other people. Many of the members have written articles and ideas about 'weedy' plants and the discussions in All Things Gardening are often about 'problem' plants.
If an apple tree were to grow in a wheat field it would be considered a weed. So the term 'weed' only means that the plant is growing where someone does not wish it to grow. All plants deserve a place in our database; it may be difficult to positively name a plant as a 'weed' and have everyone agree.
If you need an ID for a wildflower growing in your lawn, post a photo in the Plant ID forum and give as much information as possible; the members will provide any and all information to help you decide if you should pull it or cultivate it in your area.
Adding photos and data to the database and information in the 'Comment' section would help readers to know which plants have a tendency to be weedy and in which parts of the country/world so they may be forewarned.
