For Twitter: switch to 'Latest Tweets' or use the search "filter:follows include:nativeretweets"; unfollow everyone or make a new account, use Twitter search a lot to search for things you're interested in (I like to query for phrases that only domain experts would know about), follow intelligent-seeming people and check their following list; quickly unfollow or mute anyone who is bad at tweeting.
