About 3,500 at the moment. It sounds a lot to be holding on to but I have sold around 8,000 in the past 12 months (mainly quick flips at small profit). Therefore what I am left with is a relatively small percentage and most of them are names I'm wanting to hang onto (around 1,000 are L-L-L.com's which are one of my niches that I like). Having said all this I am still selling a few to trim it as it is still a big renewal cost each year.
I am also developing more and more. I have about 40 active websites and am getting more online each week. This is my new passion and I am heading more and more towards development and link building.
