I've recently discovered the use of Twitter lists and decided to create some useful ones for devs.
If you think someone is missing in a list (or you have an idea for another cool list), please comment :)
DevNews - A list with mostly official technology accounts. You'd be surprised, how often you can find real gems in their timelines!
Bonus point: There may occur occasional job offers from these accounts even before accounts from the DevJobs list retweet them
DevJobs - A list with Twitter accounts which tweet jobs all day long. You'll find something for freelancing and company positions here.
DevConfs - All the major development conference accounts in one place.
AI/ML/NLP - No surprises here. If you're interested in artificial intelligence, machine learning, or natural language processing, you will love this list.
React.js - Thought leaders and people deeply involved in React.js development itself.
