Depending on your industry, your colleagues and industry peers may be active on Twitter and are likely to follow you back. Follow the people you work with as well as individuals you may know through previous roles, industry meetings, and more. Often people name the Twitter handle of the company they work at in their bio, so search something like (“@intel”) for people who may work at your company.
Conferences and Events
If you attend a few conferences or events each year, you’ll meet interesting people that you can follow online. Often there will be a conference Slack group where everyone attending can chat. A link and instructions to join this group are typically provided in an email after event registration, generally weeks before an event is slated to start. Join it. Add folks to Twitter that you’re looking forward to meeting or you’ve had interesting conversations with. If you’re at a larger event, temporarily add it directly to your name on Twitter.
For example, if your Twitter name is normally “Alfred Lin,” change it to “Alfred Lin at Cool Eng Event Dec 6-10” so people know you’re going. You might also temporarily pin a tweet to your profile about being there.
