Mostly because many job sites (greenhouse.io and lever.co) ask for a twitter link along with LinkedIn and Github. I&#x27;ve found the more interesting you can make yourself when applying, the more likely you will get a follow up interview.<p>You don&#x27;t need to be a 140-char Shakespeare, just follow some influences and projects you&#x27;re interested in, re-tweet things you find useful and if you have anything of substance you&#x27;ve created (github, blog post etc) post it.<p>It&#x27;s not so much showing off as it is showing you&#x27;re on-top of new ideas and trends in your field.
