We know that gethuman.com can help you reach a real person at a corporation that has an unyielding phone tree. But there are actually many ways -- about 50, in fact -- to get the attention of the right customer-service rep.

Tip o' the hat to "vh" at Funny about Money for directing her readers to "PBX hell: 50-plus hacks and tips to get a real person at any corporation in 10 seconds or less" at VoIP-News.

For those who've been hopelessly lost in the phone-tree maze, this list could restore your blood pressure to normal.

Government Web sites provide a wealth of information about money-related topics. But finding what's out there can be a chore. This resource provides links to 70 government Web sites about everything from finding a job to buying a home and paying for college.

Just the other day, we were thinking it might be time to brush up on advanced complexity theory. And because we're expanding our vegetable garden, knowing more about soil mechanics might help. (Well, maybe not because we haven't taken the prerequisites.)

And in case we've forgotten about the particular charms and indignities of aging, we can take free courses on that too, courtesy of Johns Hopkins.

If you have knowledge gaps you want to fill, you can do it online -- for free. To help you find a particular topic, UniversitiesandColleges.org is building "The master list of free online college courses." Feel free to let them know of courses that don't yet appear.

Can a family with an income of $100,000 or more really have a hard time getting ahead? FreeMoneyFinance's recent post on that question has prompted quite a discussion among commenters at his site. FMF launched the debate by remarking on a family mentioned in one of a package of MSN Money stories about the "squeeze on the middle class."

The couple make six figures, but are unable to save. "We struggle to stay afloat with the rising costs of car insurance, gas, utilities, food and other necessities," one of the family members said. FMF's assessment: "They're simply spending too much. They have no control on expenses." He also guesses that they live in an expensive area, noting that "$100,000 per year is a lot, but it's more in Omaha than it is in Los Angeles."

You don't need to have a crazy interest-only or adjustable-rate mortgage to feel the pain of the housing slump. A reader who posted a question at Free Money Finance wisely put 20% down and got a fixed-rate mortgage in Las Vegas when that housing market was sizzling hot. Now it's not, and he's upside down -- he owes more on the house than it's worth because of dropping values.

His problem is that he wants to move.

"Free Money Finance" wrote: "This is a tough situation. He's played by the rules, been faithful, and is now left paying on an asset that's worth less than what he owes on it. And, to make matters worse, he needs to move (or at least I think that's what he's saying.) So he has to sell at a loss."

To some, 60 minutes may be a TV show, but to Kris at Cheap Healthy Good, it's the time she takes each week to implement her personal system for saving major money on groceries. With the rising price of food, this is something we all need to read about.

Before you try her system, she advocates three steps. First: Junk any food on hand "that A) you can't identify, B) is in an advanced state of decay or mummification, and/or C) is old enough to be carbon-dated."

After reading "Filling up on freebies: Where to score free food," at AzCentral.com, we thought: Writer Scott Craven wasn't craven -- in fact, he was brazen -- as he scoured the Phoenix area for free food.

From car dealerships and grocery stores to churches, restaurants and probably the most celebrated source of free samples of all (all hail Costco), Scott scored so much free food that he probably put on weight.

He proved that "there is such a thing as a free lunch. Or breakfast. Or dinner." That is, if you know where to look.

First, he set several conditions and expectations:

Some people are financially sidelined by circumstances beyond their control, while others just poor-mouth -- making excuses for their circumstances with phrases like "The poor man just can't get ahead" or "We struggle just to make ends meet" or "I work hard so I deserve it."

"Frugal Dad" calls these folks the "perpetual poor" and explains how you can identify them in this biting and humorous post. For instance, he writes, those who use the "poor man" rant referenced above "can recite the last five winners of American Idle (that's not a typo) from memory, haven't picked up a book since high school," and "never stretched to learn a new skill at work, but complain about being passed over for promotions."
