Submit portable freeware that you find here. It helps if you include information like description, extraction instruction, Unicode support, whether it writes to the registry, and so on.
Posted earlier today about this topic because I wasn't optimistic, but here we are with a portable solution. Maybe my least favorite thing about Twitter was the single account focus, so the multiple accounts capability was maybe the highlight.
Requires: Windows 7+, and .NET Framework 4.5.2 or newer
Status: Portable, writes to "portable\storage" (stealth status untested)
Steps: Download the self-extracting "portable" EXE and launch Tweetduck.exe
The first TweetDuckversion I tested was 1.8 and it was in my submission list. The program is not bad at all but the developer is a complete idiot, he is one of the two developers who deleted my GitHub comments (the other one was the developer of CuteTorrent, another program am no longer interested in)- I cannot stand such attitude so I dumped TweetDuck for good. Anyway, Twitter is a vicious censorship monster (many of the people I follow got their accounts banned) so I would suggest Gab as a censorship-free and ads-free alternative.
