I don't use Chrome. I had noticed the slowdown using Firefox.
It was unusable for me with Facebook+Twitter links.
Now that it has just Twitter, and I have less posts per page it is usable, but not as quick to load as it was before this "social network integration."
If the Twitter links are not doing much good I hope they get removed to speed up loading again.
There must be some other factor in the variability of the slowdown from person to person... Java version? Internet connection speed? Virus scanners? Free memory? Speed of the Twitter cache server local to that user?
