If you're already wondering “what's a doomby?”, then you should probably read the first post, titled “What's doomby, and how do I use it to make a website?”. To save you some time, the ultra condensed version of that post is: doomby's a free website builder, and you can use it to make a website (funnily enough). As in, make your own website, about stuff that interests you. For free.
So what, exactly, can you do with doomby, and how is it going to help you to create a website?
