Given that Diaspora has yet to be written, I doubt that J. Fried is particularly quaking in his boots regarding the hypothetical creation of a hypothetical plugin using a hypothetical API to provide a hypothetical service that would hypothetically be so great as to kill Basecamp.
Disclaimer: I dont use basecamp, have never used basecamp and have absolutely no idea why someone would want to kill it.
What matters is the trend, and Fried is smart enough to see it.
What unfair here is that he spoils it in the middle of the finance period. They got traction, they look like smart and honest guys. He can bash them one day after the finance is done.

Slashdot misses you already, the door is --->> http://www.slashdot.org/ that way.
For the record, all that Jason Frieds posting has done is give more attention to diaspora.com, and will probably result in more funding.
