Ok, so it's not the only thing to take the Electron route, but...
Skype just released an update (it's still rolling out) that replaces the perfectly (or at least, mostly optimally with a little tweaking) working native interface with one powered entirely by a single instance version of Chrome. Basically, the Skype client is now one big, weird webapp-looking thing. Windows users will love the breakage of screenreader scripts (if they use them) and all the familiar interface elements, Mac users will love the unresponsiveness and messy Voiceover navigation, and Linux users will love the blank window (Chrom{e,ium} isn't accessible, still). Everyone will enjoy the extra resource and battery usage.
Meh. I didn't mean to make that quite as potentially negative as it sounded... I do get why this was done, and if the resource usage and accessibility bugs (these are not Skype's problem directly) weren't a problem, it'd be ok. I do like the idea of easy, cross-platform development...
I'm going to post this before more is written that seems more ranty than it's meant. It'd be advisable if you haven't gotten the update to backup your Skype application data at least, so you have copies of your chats that you can export as text or HTML if you want to (remember, from five years ago, the first Skype chats with your partner/close friend(s)?)
On the upside, your screenreader will automatically read notifications and some incoming messages...
Have you gotten the update yet? What are your thoughts?
