I think it does have value, but a few things that struck me as "must dos":
- make it better for mobile, since that's likely the platform I'll use in a strange city. Maybe this is part of the graphic design piece that you were talking about.
- make it easier to see ALL the breweries/beers near me. I would think that would be the main page instead of one at a time (I hate refreshing the page)
If this project was dropped in my lap, I would do this:
- work on UX above all else (and before data entry). Make it easy and enjoyable to see what breweries are near me and to add breweries and beers.
- focus on a single geographic area for data entry. I'm in Chicago, so I would make this a killer website to visit if you're visiting Chicago. Promote it heavily in Chicago (Facebook ads is super targeted and great for something like this, you can target beer drinkers ages 21 - 40 in Chicago only, and might even be able to narrow it further).
- Let users add content for additional cities if it becomes popular in your homebase. Remember, we already made it really easy to do that in step 1.
- I might even look into signing up bars to be listed on the site as carrying a particular beer/brewery when a user is near their location. In exchange they put up your flyer. Free promotion if the functionality is there.
I think there is definitely value here, but I would devote some serious time to improving UX before data entry. As others have said, there are ways around doing the data entry, but not too many ways around good user design.
