From a usability standpoint, all the advantage of LL is on the hoster's side. For the end-user the latency is practically never adequate to prevent a frustrating experience. I use whatever GM scripts or other hacks I can find to just load the damned page, if such workarounds exist.<p>Recently eBay moved to LL in most of its searches, but this can be obviated by re-searching from the Advanced link, for instance.
This is ridiculous to me. I open a new tab in my browser and if I know it's a long page with lots of pictures, like some blog or ebay listing, I might postpone switching to the tab with the single purpose, so it loads all the content in the background and the page is completely ready for me to scroll.<p>If it's combined with infinite scroll it's even worse. In such case I need to manually scroll the page for as long as I need so it starts loading the damned content. Not many things bring me so close to the point of rage.
