As mentioned in my last post, I don't generally use keyservers. I would much rather just email the key or leave it posted on my blog. However, with that said, I do have my key published to the 3 most popular keyservers on the web, with the first as my default in both Seahorse and GPA (for obvious reasons I hope).
The main reason I choose these are because they can handle multiple subkeys and modified UIDs whereas many keyservers cannot. At any rate, I thought that I would share this, because they are solid, always up, great web interface and easy to use.
