Anyone considering attending a protest of any kind should probably at least skim over some of this guidance:

Follow the money hashtags! Seriously, if you can’t immediately find people to follow (a very common problem when people first join a social network), follow hashtags! Super easy to do:

• Search for your topic
• In the search results, switch to the “Hashtags” tab (or just scroll down to the hashtag section of the results)
• click into one of the hashtag search results
• Review the posts, frequency, etc. If you like what you see, click “Follow Hashtag”.

It really does a great job of (1) populating your feed with interesting, relevant content and (2) can ultimately connect you to new people with similar interests.
