Five things Delicious could (and should) fix

Pubblicato il: 19/10/2009 — Tematiche: bookmarking,del.icio.us,english,informazioni,segnalazioni,Web 2.0

I appreciate and use a lot the social bookmarking features of Delicious but there are some issues which detract from the otherwise great experience of the site.

So here’s a list of pleas suggestions for the Delicious team about some things they could (and should) fix in the next version/revision.

  1. When you click on the “save” button to add a bookmark to your account, Delicious could (and should) also copy the valuable “Notes” field (i.e. the description)
  2. In the same way it could (and should) also copy the tags. In the meantime there’s a nice javascript bookmarklet that does it also adds a via:username tag
  3. Delicious send - Twitter @Disable the global “send” (i.e. sharing) of all bookmarks on Twitter and make it only a per item option.
  4. Also: when sharing on Twitter Delicious could (and should) add automatically the title of the bookmark since the url shared on twitter show up as just a “mistery meat” icio.us with no clue about the content and destination.
  5. In the Network list it would be nice if the apostrophes wouldn’t show up as Html entities

Your own url shortener: the way to go?

Pubblicato il: 13/08/2009 — Tematiche: cms,english,informazioni,risorse,segnalazioni,WordPress

An url shortener allows you to create shorter URL’s and (sometimes) keeps track of how many times a link has been clicked. On the other hand, relying on third party services may have quite a few side effects.

According to Jeffrey Zeldman the solution is rolling your own mini-URLs [which]

lessens the chance that your carefully cultivated links will rot if the third-party URL shortening site goes down or goes out of business

If you are running for WordPress there are two solutions available, both in the form of installable plug-ins.

One is the Short URL Plugin which Zeldman recommends.

The other is La Petite Url which, John Gruber notes, includes support for Short URL Auto-Discovery.

“Apple strongly cautions against installing any software that hacks the iPhone OS.”

“Apple strongly cautions against installing any software that hacks the iPhone OS. It is also important to note that unauthorized modification of the iPhone OS is a violation of the iPhone end-user license agreement and because of this, Apple may deny service for an iPhone or iPod touch that has installed any unauthorized software.”

Unauthorized modification of iPhone OS has been a major source of instability, disruption of services, and other issues
