That said, IMO this article is not about Craigslist but a subtle advert for the 2 "competing firms" that are mentioned. I have seen an uptick in articles about Craigslist mentioning them and had never heard of them before.
Potentially cynacism on my part.
"craigslist" + "offerUp"
You will see a lot of articles about how Craigslist makes money; is dangerous; potential revenue models; is going to finally get dethroned.
The one that made me think a campaign to promote these 2 companies was about bad site design.
Figure very low costs for a site like that you could make your money back in 5-6 years; which is insane at that scale. I bet if they put it up for sale for $3B it would be sold by the end of the week
At P/E ratio of 5, you literally just wait 5 years and you've just made as much as your initial investment.
Therefore I would pay 10B for craigslist in a heartbeat. I could probably even get a bank to loan me the money.
