A few things to note Rated 3 out of 5 stars

3x stars because I cannot move the button in Firefox 28.0 Also why the hell did you delete reviews?

1 star for dishonesty Rated 1 out of 5 stars

Deleting reviews is deceiving the public. It is wrong and this is not a 5* service.

Rated 1 out of 5 stars

Doesn't work properly in Firefox 35.0.1. Clicking the button in the toolbar will just open my pearltrees profile without adding anything to my collections or my dropzone, etc. Clicking the star that sometimes appears next to videos or links on website will just prompt a popup asking me to login or register, either of which will again, simply redirect me to my Pearltrees account, effectively doing nothing. Super useless.

Bug sur la pop-up d'ajout d'une perle d'un autre dans les miennes. L'image derrière reste dans la pop-up me demandant où je veux perler.

Democritize web organization!.. by censorship Rated 1 out of 5 stars

Oh, so that's what you meant by 'democratize', huh? I've certainly seen some of the * reviews being deleted, but I didn't say anything on that matter - well, author could've changed their opinion and deleted reviews themselves. Well, ok, stuff happens, right?
But hey, I certainly didn't delete my review and guess what? - it's missing! So, censoring negative reviews that are not convenient for you is a part of your 'democratize web orgaization' policy, huh?

It seems that developers can't take a fair criticism and are allergic to negative opinion. Well, here you go, try not to sneeze:

Squarefolds is nothing close to the product which received so much positive reviews. It was Pearltrees. Did you notice that there's almost no positive reviews for this product that came after May. Well, that's because they've taken everything, that was good in Pearltrees - customization, organization, trees, pearls. Instead of unique pearltrees that you had in version 1, not you just a pile of square icons, tossed in a folder.
Squarefolds is just a... disappointment.

P.S. Let's see how long this review lasts.

"Spearltrees in Spanish" Rated 5 out of 5 stars

El complemento y la página Spearl es muy bueno. Pero, me gustaría aún mas si fuera en Español. Espero que, tal vez algún día, salga en ese idioma. Aún así, como dije antes, me gustó. Le pondré 5 Estrellas. >=)

Saludos!

Awesome! A more stylish way and easy way to organize my favorite sites. Glad I came across this and decided to try it out. I prefer it over the default bookmark option. Thanks.

Good Solution Rated 5 out of 5 stars

Best yet, you can preserve that page in case it disappears.

More than bookmarks Rated 5 out of 5 stars

Pearltrees is a perfect tool for me and the way I use information, think about subjects (I have A LOT) and organize them.

Quasi mind-mapping with the ability to curate, annotate and find similar from other dedicated users. Since users are global (company is in France), you will have a better chance to find stuff that the big search engines ignore.

One of the few apps I pay for.

If you go Premium, you can do more than comment on a link. You also can make trees private. Best yet, you can preserve that page in case it disappears.

I can't stand linear bookmarks because that's just not how my mind works.

Fun way to order all your favorite sites together and see who shares your interest. I also like the option to discover new sites in a quick way.

The only downside is the fact that I can't seem to find a simple "Log Out" button anywhere, maybe I am not searching good enough or it's not really clear at all.

Long time fan of this early social bookmarking site that recently opened up premium memberships (option for private pearls). Great way to find similar sites or use it a search engine.

This is fun and the ui is beautiful, It feels a bit like wikipedia, you move, and move and learn stuff. It's easy to get stuck and goes too far.
