Which of the following microblog practice is similar to the content curation capabilities of a blog?

A) Hashtags
B) Crowdsourcing
C) Links to Wikis
D) Retweeting or forwarding messages
E) Sandboxing

Retweeting or forwarding messages is similar to content curation as it involves sharing and amplifying valuable or relevant content from other users on the microblogging platform. Just like a blog curator would selectively share content from other blogs, microbloggers can use retweets to share tweets that resonate with their audience. Hashtags, crowdsourcing, links to wikis, and sandboxing are not directly related to content curation in the context of microblogging.
