okaay, so there's now 10 potential useful articles to read, they're already loaded (yippee, saves time...) hmmm let's go through them hmm... that one's useless (close) that one's useless (close) that one looks interesting but i don't have time to read it immediately....
---->>> LET'S KEEP IT OPEN FOR NOW * <<<< ----
.... and move on whoops the phone's ringing i have to deal with a client's urgent issue, he also needs something to be fixed okay so it's an obscure issue i don't know anything about let's do some google searches damn we're under time-pressure again let's do the same trick, right-mouse-button on a stackexchange liiink, right-mouse-button open-in-new-tab on a forum paaaage, right-mouse-button on some git repository browser because i might need to compile that up or investigaaaate...
okay now the tabs are open and loaded don't have to wait for them to load let's review them... close, close, read, read, close, read.... hmm that looks like it's got the info i need, but...
---->>>> LET'S KEEP THE TAB OPEN IN CASE I NEED IT AGAIN TO FIX THE CLIENT'S PROBLEM IN THE FUTURE <<<<<----
okaay so i have time to go back to that particle physics research now and i can carry on where i was interrupted ...
--->>>> * BECAUSE I LEFT THE TABS OPEN.... * <<<<-----
repeat, repeat, repeat, repeat. the technique saves vast amounts of time (through proper use of parallelism), uses the browser itself as a proper research tool, as well as an information storage mechanism "with history". the actual "browse history" itself i have found to be pretty damn useless, i can never find anything as it doesn't have a proper useable UI.
from your enquiry i should imagine that you're one of these people who sits there waiting for a page to load, sequentially, then closes it... sequentially. depth-first in other words. by which time it's been so long that you've forgotten what you were searching for. for those people who use internet search engines to do breadth-first searches, tabs are absolutely invaluable.
