I try to find topics that are not being covered well elsewhere, but for the main headlines and inside information about the current Gaza op I recommend these three essential blogs:
Aussie Dave at Israellycool has been liveblogging from the beginning, with a bemused attitude. Lots of links to insightful/interesting/humorous pictures and videos.
Jameel at The Muqata has likewise been liveblogging, a bit straighter than Israellycool but with many links you wouldn't know about otherwise. He also is tweeting on Twitter.
Omri at Mere Rhetoric has been writing posts at a mind-boggling pace. His writing is wonderfully sardonic, amusingly snarky and extraordinarily link-dense. Those links bring up a complete hypertext world of relevant facts that we've all seen and forgotten.
