What these three articles are talking about is the nefarious filibuster. A senate tactic that allows the minority party to block legislation, unless there are 60 senators to overturn said filibuster. Currently the Democrats have 53 seats, plus 2 Independents who are expected to caucus with the Democrats, while the Republicans have 45.

It seems obvious that the reason this is being talked about is because the GOP is filibustering much of the Democrats' proposed bills. So is it a good idea?
The Washington Post articles flesh out the story a bit more, and the WP Opinion article -- written by Richard A. Arenberg who apparently worked closely with both the House and the Senate -- in particular is very informative. The best highlights are as follows, first from the last link:
"Republicans say they filibuster legislation because Reid blocks them from offering amendments."And second, from Arenberg's opinion piece:
"No one should be fooled. Once the majority can change the rules by majority vote, the Senate will soon be like the House, where the majority doesn’t consult the minority but simply controls the process. Gone would be the Senate’s historic protection of the minority’s right to speak and amend. In the House, the majority tightly controls which bills will be considered; what amendments, if any, will be in order; how much time is allotted for debate; and when and under what rules votes occur. Often, no amendments are permitted."
So what it comes down to: Would it be good for the Senate to operate similarly to the House? That whatever the majority party is would simply have command?
I don't know.
Ideally, both parties would be able to compromise and work bipartisan manner, but it's a far from ideal world. Likewise, it seems that the filibuster is an important -- if frustrating -- tool in the checks-and-balances department from giving one party too much power. Thereby, theoretically, forcing cooperation and compromise. With it gone, and only needing a simple majority, there'd be no incentive.
