>Do you think that you will get bored of 4chan
No, and despite what some doomsayers like to claim, the site has a remarkable rate of user-retention. Sure, posters take breaks lasting months or years, but eventually they come back. There just isn't anything like imageboards out there. It's a system designed for engagement over subjective "like" or "dislike," where the content of post matters more than the poster. If a thread is not engaging enough, it gets bumped off.
Also, the range of discussion you can have is superior in its coherence and versatility. You reply to individual numbered posts, not posters. With this not only is back-linking and forward-linking through conversations so much better than other sites, but you can address multiple posts (again, not posters) at the same time making more complex discussion lines possible.
