    The premium nature of Upstack’s services can make it more expensive compared to other freelancing platforms, which may be a barrier for startups or small businesses with tight budgets.
  • Limited to Development Roles
    Upstack primarily focuses on software developers and engineers, which might not be ideal for companies seeking a broader range of roles such as designers, marketers, or other specialists.
  • Geographical Restrictions
    While Upstack has a global talent pool, certain companies may prefer or need developers in specific time zones or regions, which might limit their choices.
  • Onboarding Time
    The thorough vetting process, while ensuring quality, can also extend the time required to onboard a developer relative to other more immediate gig platforms.
  • Dependency on Platform
    Heavy reliance on the platform's tools for communication and project management might be challenging for teams already entrenched in different workflows and tools.

Duolingo Reviews

  1. A review

    It's incredibly easy to use and the regular reminder from the app about practicing more keep you consistent. Besides,in my opinion,it also can be not only a tool for learning languages,but a good entertainment for kids too. I've been practicing here almost every day throughout the year and i highly recommend Duolingo:))

    👍 Pros:    I added everything i want to be mentioned above
    👎 Cons:    Perhaps the design may look "too childish" for some adults,but it's only the matter of taste
  2. Pretty good

    Duolingo is a quite nice language learning app for the begginers and for those who want to know a certain language on a pretty good medium level(It's like something between A2-B1,i suppose). Moreover, I'd like to admit it's can be useful for kids as well because the app has cute design and playable interactions , challenges and its own little app - shop where you can buy different bonuses for you ,and in my opinion,children could like an idea of learning languages in a playable form. Though, Duolingo can be rather annoying, when you miss one or two days of studying ,so it'd be really awesome if my brother,for example, who uses this app ,could make his own studying schedule here.

  3. Best Language Learning App
    👍 Pros:    Supports multiple languages|Variety of languages|Tasks|Daily routines

  • A responsibe layout with a single breakpoint - how to replicate ?
    Just wondering if you could help me. Spotted this website https://upstackhq.com/ which is awesome as it is perfectly responsive at every viewport width and has only one breakpoint. Every element actually has a variable width or font-size or anything to size it, that is not fixed. This gives a really smooth feeling to it. No "jump" in layout such as with a classic responsive page with breakpoints. Source: almost 2 years ago

  • how gamifying my life helped me build better habits and achieve my goals
    Duolingo: a language-learning app that uses points, levels, and rewards to keep you motivated. This is the most effective when you do it with your friends or a group of people who share your learning goals. I got really addicted to checking my leaderboard rankings everyday.

  • Brushing up on Spanish
    Hi! I wish I'd seen a post like this a few months ago. I would have been interested then. By now it's a little late for me. I just signed up for the 2 week free trial since that's about all the time I have left before I leave. If you can, use a desktop computer/laptop to do duolingo.com and it will have no ads and unlimited hearts! Not as convenient as the app on a phone but saves tons of time and you can do it...
