nerd. check out my tree. Create a Pearltree (like a folder) add a pearl (bookmark). If anyone post the same pearl (bookmark) youll be notified via the medium of electronic mail. You can then check out their Pearltrees. If someone likes your stuff, they can grab your Pearltree (folder) and stick it in theirs (oooh errr). Your now linked. If they update their Pearltree you see their stuff. Me and you are linked cos I grabbed your Original Pearl (the centre one) and stuck in a folder (pearltree) i created called friends. Fatties following the same process. Good eh! You can actually tweet stuff as well via the medium of Pearltree.
