Always worth checking that the page size is 101k or less, despite all the others who have happily linked. I thought that I had found a world record a few months ago with 285k but a real estate site I found today beats them all, 885k.
885k is nothing. I regualrly see pages over 1mb and sometimes over 2mb. I do not seek these pages out, because there are better pages to seek. The reason why people are still signing these pages is because they are in a database and are automatically signing it. As for the 101k limit, you can go past that quite a bit and search engines will still give you some benefit.
