Suggestion: wherever the information is available (with the understanding that it's usually not public), a very helpful thing to know is what the conference's default policy is on travel/lodging for speakers.
If a conference is far away, but pays for travel and lodging, that's very different than if you're going to be out a lot of cash if you want to speak there.
Knowing this up front can make a big difference in deciding whether to submit a talk.
I'm planning on adding filtering to the site and email notifications. However, right now there aren't that many new conferences each week (<20), so it's easy to scan through them.
(I don't want to detract from this post, just want to make people aware of the data we have. Having a dedicated service that curates and emails out this kind of information is definitely a plus for the community - our CFP feature isn't particularly well publicised)
Location, but needn't be too localized. (I think most people travel nationwide)
I'd filter on language, but also include "concepts" (for instance, mobile, or startups). You also should identify conferences which aren't immediately obvious what the language is, or that cover other languages. (for instance, RIACon was traditionally a ColdFusion conference, but in recent years has added a JavaScript track; Ruby conferences usually have some functional talks, etc)
Honestly, I'd initially just filter by region or continent. Going down to the country region only adds complexity for people who don't mind traveling to countries nearby. And the volume of conferences isn't SO high that you'll get a huge list by selecting just a continent.
Or maybe "technology". For instance I'm only interested in speaking at iOS/app conferences. I speak on design, programming, and business. So, a single language isn't as important to me.
This site shouldn't really be called "call to speakers" but "call to attenders". Only last 3 conferences on the list have still open call for papers/speakers. From the other last one closed in July. The deadline counts down to the conference not call for papers deadline. The site itself doesn't really provide any useful information for submitters. You have to dig it all up yourself - I'm wondering beside giving a list of conferences (in pretty near future, cause conferences in March that are last on the site will be closing call for papers pretty soon) - what is the value added?
Not sure you're looking at the same list. All conference on the front page have open calls for speakers. The deadline counts down to close for the call, not the start of the conference.
What other information are you looking for? I provide the link to the application, as well as all important dates for the conference.
Speaking of speakers: The official deadline has just past (we just missed this!) but I'd love to have some HNers submit for DevOps Days Toronto here: http://devopsdays.org/events/2014-toronto/propose
Yep! The account is set up to tweet once every three hours. Each conference will be tweeted three times: when it's added, 14 days before closing, and 3 days before closing.
