Bye bye Delicious, Hello Pearltrees!

I’ve been playing with Pearltrees  and I’m impressed.  I’ve been worried about the demise of delicious since news leaked about it disappearing the other day.  I like to keep my links on the web, I hop from machine to machine and have a list of favourites in IE and firefox, but I like the way that Delicious lets me tap into what others rate as an informative website or set of links.

Well, from what I’ve found so far, Pearltrees seems to have the components I need.  Pearltrees does 3 things:

  • organize web bookmarks in the form of thematic (pearltrees) maps
  • connect to other maps and include them in your own maps
  • to discover a particular contact by sharing your profile information

There’s a youtube video explaining how it works:

intro to pearltrees


I like the simplicity of the UI.  I like the way that if I search for a topic I’ll find everything associated with that topic that others have categorised and I’m interested in this form of Gameplay and social discoveryimage

I like the fact I can connect to the source of the information – and remember it later.  I can link to other useful Pearltrees and be kept up to date with their additions to their tree – neat.  And I really do like the UI – its easier to get my head around how to organise things.  Much better than simple tagging. 

I was gutted that Delicious might go – but now I’ve found a great alternative and won’t mourn its passing as much as I’d thought.

What do you think about Pearltrees? will it succeed??

Quora: Reverse blogging will be the Twitter killer


I’ve been playing around and watching Quora for a while now.  It seems to be exploding in popularity and growing like crazy since it’s release to beta last year.  So what’s the key difference between this and Yahoo answers, Facebook or the old Live QnA  or Google answers then?

Well Quora allows you to ask a question and get answers back in almost real time.  You can search for a question, follow the users who vote up questions, or follow topics or users that answer questions.   It’s much more than a knowledge base as the responses to the questions are continually refining and improving the answer.  Wikipedia appears to be totally static compared to Quora, with infighting between anyone who wants to edit the page and the original wiki authors.  Quora appears to have valid technical responses from people who actually know the answer – who don’t speculate or create rumour, but have all of the details to respond to the question posted.

Like for example Steve Case, former CEO of AOL who responded to a question about how much it actually cost to distribute AOL CD’s in the 1990s with the former Chief Marketing Officer of AOL Jan Brandt adding to the comments.  These are credible people who didn’t need to guess – but who actually had the answer..

Unlike a blog, when you think of something to say and people hopefully respond to your post on Twitter, Facebook or Linked?In (or on the blog itself) Quora gets its content in a different way.    They call it reverse blogging – blogging as a response to a question.  There’s a huge investment of time involved in blogging.  Time spent researching, reading and crafting your post.  You publish it – and you hope that someone will respond to you, validate your credibility and cement your presence online.

Answering a question on Quora does all of this in a flash.  Your reputation increases, your profile gets known by others and you find like minded people to engage in discussions with.

Its proactive too, with alerts when someone answers a question you’re following, or follows you, or answers a question you pose.   The links are clickable, so you can se who you are engaging with and whether they are worth following or not.  With Search exposing your profile in Quora anwers, then your SEO results can only improve.

There’s a lot of work that needs to be done on the site design and usability yet but I think that Quora has the makings of a Twitter killer here.  Milo says that Quora will be bigger than Twitter.  I think in time, he’s going to be proved right…
