In business, what has replaced social bookmarking in helping users find the most relevant, high-quality information, collect it, and share it with others?

A) Social curation sites
B) Social media
C) Social networks
D) Social conferencing

Social curation sites, such as Pinterest and Reddit, have become popular in helping users find and share high-quality information. These sites allow users to curate and organize content based on their interests and share it with others in a visually appealing way. Social media and networks can also be useful, but they do not have the same level of organization and curation as dedicated social curation sites. Social conferencing, while useful for communication, is not directly related to finding and sharing information.
