Quick suggestion: could you show the summaries directly on your first page, without the user needing to clicks links? (Otherwise, we are back to part of the original problem: need to open many tabs to read each story's summary, or do a lot of back and forth between front-page and post's summary).

In case there would be too much text when doing this, another way to solve this would be to unroll the summary dynamically when user clicks "summary" (instead of opening a new page). Hope this is useful!
