Mercury is a personal planet, ruling your communication style. His sign and house position as well as aspects show how you get your point across, how you learn, how you listen (or if you even do), the tempo and rhythm of your mind. and what stimulates you mentally. Uranus is a generational planet, and is erratic, all over the place energy. His location tends to show areas where you'll experience unrest and constant change. You can't experience "normal" with the areas of life ruled by where Uranus is in your chart, they'll have to be different in some way, otherwise things won't work out. Often Uranus is the most difficult in the 7th house, the house of relationships, because many people with this position will try to fight the fact that they can't have a "conventional" relationship or be with a "conventional" person to their detriment. Embrace the zaniness of Uranus, and you'll have a lot less problems.
In prediction, Mercury shows what areas of life you'll be mentally focused on or will be having the most conversations about (even if it's just with yourself). Difficult aspects to your Mercury can show fights, misunderstandings. Uranus shows where life will be erratic; this can be unstable, unsettling energy if you don't try to use it right, or it can bring much needed change, new scenery, breath of fresh air, all that nice stuff. We can't keep everything exactly the same forever! The only constant in life is change, right?
Mercury rules Gemini and Virgo, and the 3rd and 6th houses; Uranus rules Aquarius and the 11th house.
