I believe TW can be a great experience for many devs. But hey, don't trust posts of their own people on the matter. This is a company where it's standard practice for big wigs to post not only technical content, but also "evangelising" stuff to attract other employees. Read glassdoor reviews from current/ex employees and check how it feels for you.

Some people love it to the point of religious fervour, while other hate it as if it murdered their mom savagely. So make sure it looks right for you before applying for a job there.
