It's not 'dumbing down' the process. It's making it clearer for the end user what exactly your site does. If someone on HN couldn't figure it out - you've got problems.

For example, Change from "Enter a name for your drop" to "Enter a name for your file drop"

On your title it could be - "dropsauce - Drop off your files at Dropsauce & share them"

Right now your site looks like it's about naming your drop. Not about putting files which can be password and time protected.
