After 3 years, we settled our lawsuit with craigslist today. As part of the settlement, we’ll no longer be including craigslist users’ listings in our search results. However, PadMapper is not going anywhere, and we’re excited about what we have in store. PadMapper has over 100 sources of listing data, and over 700,000 non-craigslist listings [...]

Scammy Email Gems

Here at PadMapper, our servers automatically screen emails that go through PadLister, to monitor for scams, and ban listers who send scammy emails. Before we ban them, though, we have to review them by hand to make sure we don’t ban a legitimate person by accident. Because of this, we get to see a lot [...]

Massive Rewrite in Google Maps V3!

Well, I did it. I finally got around to rewriting PadMapper in a newer version of Google Maps. I’m probably one of the last developers on the planet to upgrade to Google Maps v3. Why? Well, I really, really liked Google Maps v2. That, and I wrote more extensive v2 code than most, and many [...]

Good night, sweet PadMapper Bar

Craigslist has decided to make it impossible for the PadMapper bar to function with their listings, so now, those listings won’t have the PadMapper bar on them. Sorry everyone. If you want a consistent experience, you can filter out Craigslist listings by clicking Show More Filters and looking to the bottom to see the source [...]

Neat Rental Analytics

Every so often, I get requests from researchers for rental data/statistics to analyze, and they frequently yield some interesting papers and visualizations. One of them just posted some great visualizations of median rents and rent distributions that she extracted from some PadMapper data. She seems to have been more rigorous with her assumptions than most [...]

Vacation Rentals!

You may have noticed a small addition to the filter box – a little checkbox called “Vacation”. It’s probably temporary, but for now that will let you filter for/filter out nightly/weekly vacation rentals. The prices are still quoted by the month, though, so if you see any outrageously expensive seeming places, that might be why. [...]

Bringing Craigslist Back

I’ve been wrestling with whether to bring back Craigslist listings in the search results. I’ve found a way to include them that I’m told is legally kosher since it doesn’t touch their servers at all, but it still seems somewhat dickish to go against their wishes in this, and I’ve always had a lot of [...]

Help Replenish Landlord Listings on PadMapper using PadLister

A couple years ago, when I thought seriously that Craigslist might ask me to remove their listings and that I should have a backup plan, I created PadLister for listing directly on PadMapper. Over time it started to seem like CL was probably OK with PadMapper, so I haven’t pushed PadLister at all except for [...]

Emails/Letters to Craigslist

Thanks everyone for writing so many emails and letters to Craig and Jim of Craigslist! No response yet from Craig and Jim, but that’s possibly because it’s been the weekend. In the meantime, I thought I’d share a great letter from a PadMapper user named Jeff Standard. Missed Connections: M 4 PM Me: Starving student [...]
