Recently I got a blogging advice about how to optimize your blog:
Keep your blog size as small as possible: 15 kilobytes is fine, 10 kilobytes better. Remember: most of your visitors will use 56k modems to read your blog.
I thought this hint to be a good piece of an advice and started to implement it: I took away some useless CSS code from my blog and limited the number of displayed posts to 5.
After this I asked myself: “Is this tip really useful?” I went to one of the popular blogs I knew and checked the filesize: the main page was almost 80 kilobytes (and the feeder was about 85kB). I decided to take my previous 10 posts per page back. If the top popular blog is big & popular, then the file size won’t be a limitation to me neither (I also thought about my audience – game developers – while deciding) .
It’s always good to listen to someone’s advice, but you should test the recommendation before accepting it.
Don’t take my word for this – test it.
