[Bug]: broken tweet link under testimonials section , on homepage

### Consisely describe the issue

there is multiple broken tweet URL ,one under the Shinya Yanagihara section on the homepage , tagged as "featured link "
which probably is a deleted post, as username listed on that URL , currently has no public posts. Another anchored under Ananth Iyer , that should redirect users to their tweet , which also , was probably removed. The account (@mrananthiyer) still exists, but the specific linked tweet (status ID 1681923271267319810) returns "post doesn't exist

**suggested fix:** better to remove them completely
