Because I have a couple of half-written lengthy draft entries that I don’t have the energy to fin­ish before I col­lapse into bed for the night, I’ll share some (admit­tedly work-based) links with you instead.

Typekit
Typekit can be sum­mar­ised as font replace­ment through javas­cript, which in turn can be sum­mar­ised as “magic hap­pens”. I’ve not played around with this as much as I’d hoped, but if you read this on the site (as opposed to the RSS feed), you’ll notice I’m using it for entry titles (and all other h3 ele­ments, too). Dis­turb­ingly easy to imple­ment, this is some­thing I’d genu­inely pay for if the choice of fonts improves.

Brizzly
Man­aging more than one Twit­ter account? Brizzly is the best solu­tion I’ve found, mak­ing it suit­ably dif­fi­cult to announce your per­sonal secrets to your work account. Now includes Face­book integ­ra­tion and has seem­ingly man­aged to get over a bizarre bug where it finds search res­ults over and over and over again, announ­cing them as new every time. This wouldn’t be so annoy­ing had I not pos­ted the tweets that triggered the search find­ing in the first place… (Still invite only, I think. Leave a com­ment or send a mes­sage to @whoopdedoo on Twit­ter if you want one).

Mobile web­site devel­op­ment
Without giv­ing any­thing what­so­ever away about what I’m cur­rently look­ing into for work purposes:

• Smash­ing Magazine on Mobile Web Design Trends. Des­pite my own pre­ju­dices,  Smash­ing Magazine do actu­ally pro­duce con­sist­ently use­ful art­icles, all of which must include the word “trends”.
• Cameron Moll: Mobile Web Design Book.
• Jakob Niel­son: Mobile Web Usability
