Comments and Reviews
I've tried every twitter client for Linux and by far this is the most user friendly, discreet client with many features you won't find to the rest.
Same here

i like the minimalist deal with hotot -- im a freeware/open source software trying junkie and hotot is a lesser known twitter app (and especially great as a chrome/chromium extension)

I got told it'd be glitchy but I installed via PPA in Ubuntu 10.10 an it runs brilliantly :)
At last a GNU/Linux client for Twitter/Identi.ca with style and efficiency ! Tanks you guys for this app :)

This is a real up-and-comer. Slick, fast, and surprisingly stable.
