LOL. Dude, I'm trying to help you. Do you often tell people their ideas are bad when they're trying to help you?

I've worked in marketing for 12 years, with companies like Netflix and Disney. This is what I've learned on the subject, condensed into a few small paragraphs for your easy digestion:

What we're talking about here is branding.

Branding is about clarity of purpose. Your brand is your north star in marketing.

The best tool you have in standing out in someone's mind is your brand's name, because it is the smallest piece of information that encodes the following things: WHAT you do, HOW you do it, and WHY you do it. Apple - easy to remember, implies that anyone can learn it (everyone learns that "A is for Apple" when they begin to learn the alphabet).

Marketing is about positioning. Positioning means getting people to think about your company in a particular way. If they think about it in the wrong way, you could have the greatest product/service in the world and nobody would care.

The greatest obstacle you have in getting people to understand your "why" is memory/attention (two sides of one issue - cognitive bandwidth). Since you are a startup, you do not have the resources to try to win the battle for attention. Other companies have far greater ability to do that because they have huge amounts of capital, in various forms. Therefore you must resort to articulating your solution to an important problem so clearly and precisely that it sticks in people's minds and becomes easy for them to recall in conversation. This is the crucial threshold.

Can you imagine (or have you experimented to see whether this is the case with your name options) that users can and will repeat your company's name? If it's akward for them, they won't. If the name isn't self-explanatory, it likely also won't come up in conversation. By self-explanitory, I mean that you have two hurdles to clear - first is the spelling. Can you say it out loud and reliably communicate the URL without having to manually spell out the spelling? And part two - does the name itself imply the solution (or at least a general "approach" or "value", like apple's "easiness") to the problem you're attempting to address?

In the case of bookuary.com and bookfilia.com, you are not clearing either of those hurdles. Bookhead.co is a maybe on the spelling (though you do have to spell out ".co" rather than leaving the domain suffix implicit, which you could do if you chose a .com), but Bookhead still does not imply a solution, approach, or value.

I too am developing a startup in the book space. I went with Quick Reads. The what, how, why, and value are all right there, easy to spell, and easy to remember.

Aim for something like that.
