Last week, we started a new feature in which we post some of the best reader comments we’ve seen in the past week.

Here are our picks for this week, in no particular order. You’ll notice that one of them is from a rather high-profile commenter, David Simon, creator of “The Wire,” who weighed in on a story about the student newspaper he edited when he attended Bethesda-Chevy Chase High School.

If you see a particularly smart, insightful or pithy comment you want to recommend for comments of the week, drop us a line at comments@washingtonpost.com.

Story: Supreme Court expresses doubts on key constitutional issue in health-care law

Slowly but surely, I am coming down against the Affordable Health Care Act, but it has very little to do with the mandate. The biggest problem with our current health care system is that it is overly complex, inefficient, and almost impossible for the ordinary consumer to navigate. It does not operate as a market in any sense, since patients often do not price procedures before obtaining them, and few people can actually choose their own private insurance company. Most are stuck with the employer’s choice.

(Photo by Allen Goldberg) The Post delivers compelling, original journalism almost every minute across a variety of interests. But with so many stories, it’s natural for some to slip past your radar.

Not to worry. We combed through the most popular stories of March — a mixed bag of our most read and shared pieces, along with some of our favorites — to pull together the Post Most Reads: the top stories from March that you don’t want to miss.

These terrific stories are not a definitive Top 10 of the month, but do a offer smart, fun, engaging selection. Grab one now or bookmark a link using the save function Read It Later, a simple tool we’ve included to make these stories even easier to curl up with.

Note: We want to include you in this process. Is there a story from last month worth recommending to Post readers? Drop a link in the comments and we’ll feature some of the best suggestions.

Who is the Route 29 Batman? This guy.

The Washington Post has announced the hiring of John Temple, the former editor and publisher of Rocky Mountain News, as a new managing editor. He will oversee The Post’s local coverage and digital initiatives. Below is the full announcement.

The Washington Post today announces John Temple will join The Post as a managing editor, overseeing coverage that predominantly serves the local audience and acting as the newsroom’s senior digital editor.

Temple is a former editor and publisher of the Rocky Mountain News, a former vice president of the E.W. Scripps Newspaper group, and most recently, the founding editor and general manager of Honolulu Civil Beat, an online news site co-founded by eBay founder Pierre Omidyar.

“As a reporter and editor with decades of experience running local newsrooms and as a leader who has successfully launched a number of pioneering digital news projects, John’s background is ideally suited to the role he’s taking on at The Post. As a managing editor for The Post, John will ensure that the coverage we provide to our print and digital audiences is smart, original and acutely attentive to our audience. He’ll help us to build on the rapid growth we’ve enjoyed recently with readers who come to us through our website, on mobile devices, or through new platforms like the incredibly successful Washington Post Social Reader on Facebook,” said Marcus Brauchli, Executive Editor of The Washington Post.

A few hours ago, the Post launched a branded channel on the social sharing site StumbleUpon.

A screenshot of The Post's StumbleUpon channel.For those unfamiliar with the site, it works similarly to the music site Pandora by allowing users to “stumble” between full pages from around the Web based on their preferences (humor, politics, education, etc.) and then vote pages up or down to fine-tune the results being offered to them.

You can follow our channel by clicking here.

We’ll be doing our best to serve up an eclectic mix of our best journalism — politics and style; investigative reports; and graphics. To help keep us from stumbling in this new effort, we’d love to hear from readers on what kinds of content you’d like to see us share on the platform. Tell us in the comments or tweet at us @washingtonpost.com.

We have long known that our readers are much more than “readers.” Among the other things they (you) do on washingtonpost.com is write. You post tens of thousands of comments every day, in fact.

This week, we’re starting a new feature in which we’ll post some of the best comments we’ve seen in the past week. Here are our picks, in no particular order. In future weeks if you’d like to recommend one to us, drop us an e-mail at comments@washingtonpost.com.

Story: Trayvon Martin and dangerous times for black men

The Martin family cannot ever get their 17-year-old boy back. They’ll never see him grow to be a man and build his own life. But the rest of us might change as a result of his death, and the next 17-year-old with dark skin and a bag of Skittles might get a wave and a hello instead of a death chase. Could we make that our gift to the Martins as they grieve?
